Caller Unknown

A road trip across America with her teenage daughter was meant to be much-needed bonding time for Simone before Lucy leaves home for university.
But on the first night of their stay, in a cabin deep in the Texan desert, Simone wakes to find Lucy missing and a mobile phone in her place. The phone rings and the voice on the other end issues instructions: Don’t tell the police. Come to this location.
Be prepared to do a deal… There is nothing Simone wouldn’t do to save her daughter. Hide the truth. Commit a terrible crime.
Become a wanted woman. But this is no ordinary kidnap and ransom. Getting Lucy back is just the beginning.
