"A bold and expertly plotted page-turner." --Courtney Summers, New York Times bestselling author of Sadie

From the author of The Cheerleaders, comes a thriller about best friends on a weekend getaway that goes horribly, dangerously wrong.

THREE BEST FRIENDS, A LAKE HOUSE, A SECRET TRIP -- WHAT COULD GO WRONG?

It was supposed to be the perfect prom weekend getaway. But it's clear something terrible happened when Claire wakes up alone and bloodied on a hiking trail with no memory of the past forty-eight hours.

Now everyone wants answers--most of all, Claire. She remembers Friday night, but after that . . . nothing. And now Kat and Jesse--her best friends--are missing.

What happened on the mountain? And where are Kat and Jesse? Claire knows the answers are buried somewhere in her memory. But as she's learning, everyone has secrets--even her best friends. And she's pretty sure she's not going to like what she remembers.
