From #1 New York Times bestselling author Marieke Nijkamp (This Is Where It Ends) comes Before I Let Go, an emotional thriller about a suspicious death, a friend desperate for answers, and their small town's sinister secrets. Best friends Corey and Kyra were inseparable in their tiny snow-covered town of Lost Creek, Alaska. But as Kyra starts to struggle with her bipolar disorder, Corey's family moves away.

Worried about what might happen in her absence, Corey makes Kyra promise that she'll stay strong during the long, dark winter. Then, just days before Corey is to visit, Kyra dies. Corey is devastated-and confused, because Kyra said she wouldn't hurt herself.

The entire Lost community speaks in hushed tones, saying Kyra's death was meant to be. And they push Corey away like she's a stranger. The further Corey investigates-and the more questions she asks-the greater her suspicion grows.

Lost is keeping secrets-chilling secrets. Can she piece together the truth about Kyra's death and survive her visit? Perfect for readers looking for: Mystery books for teens Bipolar teen characters Asexual characters Praise for Before I Let Go: A New York Times Bestseller!
