Would you become a fugitive to save your child Another astonishing high-concept hook from the author of million-copy bestseller Wrong Place Wrong Place 'Your children are only ever on loan to you...' Simone's holiday with her teenage daughter was meant to be some much-needed bonding time before Lucy leaves home. But on the first night of the trip, in a cabin in the 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 a shocking demand- Don't tell the police. Come to this location. Be prepared to do a deal... When she tells her husband, Damien, back home in England, he insists that she call the police. But Simone feels certain that there is nothing she wouldn't do to save her daughter. Even if that means shattering her life as she knows it...

An utterly original kidnap story that throbs with tensionhard to put down. -- Shari Lapena
