Hannah has been married to Owen for just over a year when he disappears, leaving her a cryptic note: "Protect her." Hannah knows "her" must be Owen's sixteen-year-old daughter, Bailey, who keeps a guarded distance from her stepmother. But when Owen's boss is arrested by the FBI, a US Marshal comes to their Sausalito home, and there's still no sign of Owen, Hannah and Bailey must team up to discover who Owen really is—and why he left them both. While evading law enforcement, unearthing long-buried secrets, and fraternizing with criminals, Hannah and Bailey begin to come to a new understanding of what it means to be family.
