The book's synopsis explains: "Before Owen Michaels disappears, he smuggles a note to his beloved wife of one year: Protect her. Despite her confusion and fear, Hannah Hall knows exactly to whom the note refers—Owen’s sixteen-year-old daughter, Bailey.

"Bailey, who lost her mother tragically as a child. Bailey, who wants absolutely nothing to do with her new stepmother."

It continues: "As Hannah’s increasingly desperate calls to Owen go unanswered, as the FBI arrests Owen’s boss, as a US marshal and federal agents arrive at her Sausalito home unannounced, Hannah quickly realizes her husband isn’t who he said he was. And that Bailey just may hold the key to figuring out Owen’s true identity and why he really disappeared.
