Sixteen-year-old Henrietta used to be happy. But that was before her family hit the national news. Before she—and the whole world—knew she was related to one of New York s most prolific serial killers.

Senior Investigator Shana Merchant readily agrees when her brother asks her to take in his troubled, rebellious daughter for the fall semester. Doug s convinced that spending a few months in Alexandria Bay with Shana will straighten Hen out.

But when Hen arrives, Shana s not so sure. She can t help but distrust the strange and manipulative teen, who binge-watches bloody movies and roams the house at night, taking things that aren t hers.

Soon, though, Shana has more to worry about than missing heirlooms when she s called to investigate the suspicious drowning of a local teenager, only to discover her niece at the scene of the crime.

What happened that night on the dark, uninhabited island of Devil s Oven? With Hen and her new friends not talking, and a community determined to keep their secrets dead and buried, Shana knows it s a race against time to uncover the truth before her niece is upgraded from key witness to prime suspect.
