70 years after Pearl Harbor drew the US into World War II, a sinister secret—remnants of covert research done by the Army—haunts the Keaton School.

Less than two months have passed since Devon Mackintosh uncovered the truth about the apparent suicide of Keaton’s golden boy and her unrequited love, Hutch. But solving Hutch’s murder has put all eyes on her in the small Keaton School community. When she is knocked unconscious on a New Year’s Eve cruise, it’s clear that her life is in danger, too. In the aftermath of the attack, Devon must attend a weekly meeting with Dr. Jocelyn Hsu, a shrink who refuses to believe Devon’s account of the “accident.”

With nowhere else to go, Devon turns to the only people she can trust: Hutch’s terminally ill grandfather, Reed, and his heirs, Bodhi and Raven. Before Reed dies, he gives Devon a mysterious journal from his youth, revealing a secret pact among three powerful families. With only Reed’s words for guidance, Devon fights to unearth the truth Reed’s enemies are still willing to kill for.
