The Grown-Up: A Thriller (Paperback) (ISBN-13: 9781662525339)

A mother vanishes. A daughter searches--down a dark and twisted trail in a bestselling edge-of-the-seat thriller about secrets, lies, and a family destroyed in one terrifying instant.

Seventeen-year-old Lies wakes up to find that her mother's bed hasn't been slept in. Her car is parked outside. And her purse and cell phone are still by the front door. After twenty-four hours, when every possible explanation is exhausted, the reality is all too frightening for Lies. Her mother is missing.

Lies's father and his new girlfriend chalk it up to another attention-seeking stunt. When authorities show little interest in a woman who likely walked away from her old life in favor of a new one, Lies is compelled to investigate on her own. But why would her mother abandon Lies and her younger brother? Why would her mother scrub her laptop before disappearing? And who are the strangers on her mother's phone?

Growing more desperate with each disturbing day, Lies uncovers secrets that turn her world upside down. Nothing will stop her from getting to the truth. No matter how shocking it may be.
