PROLOGUE
AN UNWANTED VISITOR
If anyone had peeked through my window, they would have thought it was just a normal slumber party, a festive night that involved popcorn, manicures, and six gorgeous girls from the most exclusive clique at Holl ier High giving each other makeovers, sharing juicy gossip, and plotting their next prank for the Lying Game. My iPhone had dozens of photos of past sleepovers that looked exactly like it: a shot of my best friend, Madeline, holding up a picture of a model with fringe bangs and asking if the look would flatter her heart-shaped face; one of my other besties, Charlotte, sucking in her cheeks to apply the new shade of blush she’d bought at Sephora; one of my adoptive sister, Laurel, snickering at a D-list celeb in Us Weekly; and plenty of photos of me, Sutton Mercer, looking like the glamorous, powerful “It girl” I was.
But on this particular night, something was different …
and five out of the six girls didn’t even know it. The girl my best friends were laughing with, the girl they thought was me … wasn’t. Because I was dead. My BFFs were talking to my long-lost twin, Emma, who’d taken my place.
I’d died a month ago and was now perched somewhere between the land of the living and the great beyond, watching my life continue, but with Emma as the star. Everywhere she went, I went, like we were still sharing the same womb. Bizarre, right? I didn’t think the afterlife would be like this either.
That night, I watched as my twin sister sat among my friends. Her legs were curled beneath her on the plush friends. Her legs were curled beneath her on the plush white sofa in the exact same way I used to sit. Her heavy-lidded eyes sparkled with my favorite silver MAC shadow.
She even laughed the same way I did—loud, staccato, and a bit sarcastic. Over the past month she had perfected my mannerisms, answered to my name, and worn my clothes, all with the aim of being me until my murderer was exposed.
The worst part? I didn’t even remember who killed me.
There were whole chunks of my life that had been wiped clean from my mind, and I was left wondering who I’d been, what I’d done, and who I’d pissed off so much that they’d murdered me and then tricked my sister into assuming my identity. Every once in a while I would get a sudden flash of lucidity and a whole scene would snap into brilliant clarity, but the moments before and after it? Complete blanks. It was like getting a few random screen-grabs from a ninety-minute movie and trying to make sense of the entire plot. If I wanted to find out what had happened to me, I would have to rely on Emma … and hope that she caught my killer before my killer caught her.
There were some things Emma and I had figured out: My friends all had alibis for the night I died. As did Laurel, meaning they were all cleared. But there were so many suspects left. A particular one lingered in both our minds: Thayer Vega, Madeline’s estranged brother, who’d skipped town last spring. His name kept popping up, and rumors swirled that he and I were somehow involved.
Naturally, I couldn’t remember a thing about Thayer himself, but I could tell something had happened between us. But what?
I watched as my best friends giggled and gossiped and began to wind down. By 2:46 A.M., the lights were low, and each girl’s breathing was slow and deep. The iPhone I’d sent hundreds of texts on before I’d died suddenly chimed, and Emma’s eyes sprang open as though she were expecting the message. I watched as she checked the screen, frowned, and tiptoed out of the house and across the yard. Ethan Landry, the only person who knew Emma’s true identity—apart from my killer, of course—
stood waiting for her by the curb. And there, in the moonlit driveway, I watched as they talked, hugged, and shared their very first kiss. Even though I no longer had a body, a heart, I still ached all the same. I would never kiss anyone again.
But then footsteps crunched nearby. Emma and Ethan flew apart worriedly. I was yanked behind Emma as she rushed back inside. I glanced over my shoulder just before she slammed the door, and I saw Ethan running into the night. Then, a shadow passed across the front porch. I could hear Emma’s shallow, nervous breathing. I could tell she was scared. With another jolt, I was tugged along as she ran toward the stairs to make sure my bedroom window was locked.
When she and I reached the landing, we both caught a glimpse of the inside of my old bedroom. The window was indeed open, and standing in front of it was a familiar-looking boy. The blood drained from my sister’s face as she took in his features. I let out a scream, but it faded noiselessly into the ether.
It was Thayer Vega. He leveled a smirk at Emma that said he knew all of her secrets—including exactly who she wasn’t. And I could tell, in an instant, that whatever it was he had meant to me in life was wrapped up in mystery—and danger.
But no matter how hard I tried, I couldn’t remember what that danger was.

SHE’S SEEN HIM
“Thayer,” Emma Paxton said, staring at the teenage boy in front of her. His mussed hair looked black in the darkness of Sutton’s bedroom. His cheekbones were prominent above his full lips. His deep-set, hazel eyes narrowed sinisterly.
“Hey, Sutton,” Thayer said, drawing the name out.
A nervous chil ran down Emma’s spine. She recognized Thayer Vega from his missing person posters
—he’d vanished from Tucson, Arizona, in June. But that was long before Emma had made the trek to Tucson to reunite with her long-lost twin sister, Sutton. Long before she’d received an anonymous note saying that Sutton was dead and that Emma had to take her place, and tell no one
… or else.
Emma had scrambled to figure everything out about Sutton on the spot—who her friends were, who her enemies were, what she liked to wear, what she liked to do, who she was dating. She’d come to Tucson simply to find a family member—a foster child, she was desperate for family, any family—but now she was mired in solving her sister’s murder. It had been a relief to rule out Sutton’s closest friends and sister, but Sutton had made a lot of enemies … and any number of people could have been her killer.
And Thayer was one of them. Like so many other people in Sutton’s life, what Emma knew about him she’d cobbled together from Facebook posts, gossip, and the Help Us Find Thayer website his family had created after Help Us Find Thayer website his family had created after he’d skipped town. There was something dangerous about him—everyone said he’d been mixed up in some kind of trouble and had a horrible temper. And according to the rumors, Sutton had something to do with his disappearance.
Or maybe, I wondered, staring at the wild-eyed boy in my room, Thayer had something to do with mine. A memory popped into my head. I saw myself standing in Thayer’s bedroom, the two of us locked in a bitter stare-off.
“Do what you want,” I spat, wheeling toward the door.
Thayer looked hurt, then his eyes flashed with anger. “Fine,” he snapped. “I will.” I had no idea what the fight was about, but it was obvious I’d really pissed him off.
“What’s the matter?” Thayer assessed Emma now, crossing his arms over his toned, soccer-player chest. His knowing expression was identical to the one in his MISSING
poster. “Scared of me?”
Emma swallowed hard. “W-why would I be afraid of you?” she asked in the toughest voice she could muster, the one she used to reserve for butt-grabbing foster brothers, borderline-personality foster moms, and creepy guys loitering in the dodgy neighborhoods she’d grown up in after our biological mother, Becky, ditched her. But it was all a front. It was almost 3 A.M. on Saturday. Sutton’s friends, who were downstairs for a post-Homecoming sleepover, were fast asleep. So were the Mercer parents.
Even the family’s huge Great Dane, Drake, was snoring away in the master bedroom. In the eerie calm, Emma couldn’t help but think of the note she’d received on Laurel’s car her first morning in Arizona: Sutton’s dead. Tell no one. Keep playing along … or you’re next. And the strong, terrifying hands that had strangled her with Sutton’s locket at Charlotte’s house a week later, threatening her once again to keep quiet. And the imposing, shadowy figure she’d seen in the high school auditorium just after an overhead light fell inches from her head. What if Thayer was behind all that?
Thayer smirked as though he was reading her mind.
“I’m sure you have your reasons.” And then he leaned back and stared at her like he could see right through her—like he was why she was here, pretending to be her dead sister.
Emma looked around, assessing her options for escape, but Thayer grabbed her arm before she could put any distance between them. His grip was hard, and she let out an instinctive, piercing scream. Thayer clamped a hand over her mouth. “Are you insane?” he growled.
“Mmm!” Emma moaned, struggling to breathe through Thayer’s suffocating hold. He was standing so close that Emma could smell his cinnamon gum and see the tiny freckles that dotted the bridge of his nose. She struggled against him, panic welling in her chest. She bit down hard on his hand, tasting earthy, salty sweat.
Thayer swore and stepped back, letting Emma go.
She spun away from him. His elbow crashed into a sea-green vase on Sutton’s bookshelf. It tipped over, plummeted to the ground, and shattered into dozens of tiny pieces.
A light flipped on in the hall. “What the hell was that?” a voice called. Footsteps sounded and, seconds later, Sutton’s parents burst into the room.
They moved to Emma’s side. Mrs. Mercer’s hair was mussed and she wore a baggy yellow nightshirt under a robe. Mr. Mercer’s white undershirt was messily tucked into blue flannel pajama bottoms and his hair stood out straight from his head in silver-flecked spikes.
As soon as the parents noticed the intruder, their eyes widened. Mr. Mercer inserted himself between Emma and Thayer. Mrs. Mercer wrapped a protective arm around Emma’s shoulders and pulled her close. Emma sank gratefully into Sutton’s adoptive mother’s embrace, rubbing the five angry marks that had popped up on her skin where Thayer had gripped her.
I had mixed feelings about my parents protecting Emma from Thayer. Were they simply worried because she’d screamed … or was it because of something more sinister about Thayer himself, something they knew about him from a past run-in?
“You!” Mr. Mercer bell owed at Thayer. “How dare you?
How did you get in?”
Thayer just stared at him, a hint of a smirk on his face.
Mr. Mercer’s nostrils flared. His square jaw was set menacingly, his blue eyes blazed, and a vein stuck out on his temple, visibly throbbing. For a second, Emma wondered if Mr. Mercer assumed Sutton had invited Thayer into her room and was mad that his daughter let a boy in at three in the morning. But then she noticed the way Mr.
Mercer and Thayer were crouched, as if ready to fight. It felt like something dark and hate-filled hung in the air between them, something that had nothing to do with Sutton at all.
More footsteps pounded up the stairs. Laurel and Madeline appeared in the doorway, having come from the den where the sleepover was taking place. “What’s going on?” Laurel grumbled, rubbing her eyes. Then she caught sight of Thayer. Her light eyes opened wide and she covered her mouth with trembling fingers.
