estselling author Janae Marks delivers a stunningly crafted and twisty mystery about the tests of friendships that examines what matters most when everything can change in a split second--perfect for fans of Rebecca Stead and Anne Ursu.

That clock can't be right. When Elise wakes up the morning after her birthday celebration, she's surprised to find herself in her bedroom. Last she can remember, she had fallen asleep next to her best friends at her slumber party in her basement, and it was October. But now she's alone, and her phone says it's April 8. Elise doesn't understand. How could she have woken up six months later?

No one else is acting like anything strange has happened, yet Elise can't remember the last half year. To make matters worse, her friends refuse to talk to her and Elise doesn't know why. She also has no idea how she got signed up for photography club or why her former best friend, Cora, is talking to her again. Is it a memory problem? Could it be magic? Every day that passes takes Elise further from the world she knew. Thankfully, Elise has Cora to lean on in this new reality, and the two come together to investigate why Elise woke up in the future--and, more important, how to get her back to her past and away from this nightmare.
