New York Times bestselling author April Henry delivers a true-crime-style mystery featuring a teen determined to save a missing girl she sees in a disturbing photo. 

What if you found evidence of a crime, but no one believed you?

Seventeen-year-old Willow always has a camera around her neck. She volunteers as a photographer at Finding Home, an animal shelter. When Willow stumbles upon a lost camera memory card, it’s filled with hundreds of photos of teenage girls. Some are smiling, others look unaware, and a few seem terrified.

The police tell her taking photos in public isn’t a crime. But Willow can’t seem to let it go, especially after she finds her own photo on the card. So Willow teams up with new volunteer Dare to figure out what happened to the girls. As their investigation heats up, so does the chemistry between them. But everyone around Willow seems to have a secret: Finding Home’s owner, her own mom, and even Dare. When Willow learns that some of the girls on the camera card have gone missing, she realizes the unknown photographer might be a serial killer. Can Willow find him before he finds her?
