A librarian investigates her husband's dark past and winds up dead. Now it's up to her best friend to uncover the truth.

Becca's life is turned upside down when she finds Jenn dead in the bathtub. Soon she begins to unspool the secrets Jenn kept in life, including a troubled marriage to Rick and two dead wives in his past. The more Becca learns, the more determined she becomes to get justice for Jenn, even if the clues surrounding her death aren't quite adding up . . .

Over a year before her death, Jenn begins to notice her husband acting strangely. Using her skills as a librarian, she digs into Rick's past―and falls down a rabbit hole far deeper and darker than she bargained for. She's already beaten the odds by living longer than his other dead wives. But now she fears her time is up.

This captivating story of marriage, friendship, and motherhood is a first foray into thriller by USA Today bestseller Annette Lyon.
