What happens when the people you love the most are the people you can trust the least?

In the months after Cam and Blair broke their small hometown’s legendary missing-girl story and catapulted to accidental fame, they vowed never to do it again. No more mysteries, no more podcasts, and no more sticking their heads where they don’t belong.

Until Mattie Brosillard, a freshman at their high school, shows up on their doorstep, begging Cam and Blair for help. Mattie's sister Lola disappeared mysteriously five years ago. No trace of her was ever found. Now, she's back--but Mattie is convinced the girl who returned is an impostor. Nobody believes Mattie's wild story--not Mattie's brother, not Mattie's mother, and not even Cam and Blair. But something is definitely wrong in the Brosillard family. And Blair has her own reasons for wanting to know what really happened to Lola while she was gone.

With Cam and Blair still struggling with the aftermath of their first mystery―and with new secrets swirling between them―the stakes are higher than ever in this can’t-miss sequel to Missing Clarissa.
