One mile under - Andrew Gross

The heart-pounding new thriller from the co-author of five No. 1 James Patterson bestsellers including Judge and Jury and Lifeguard, and the Sunday Times bestsellers The Blue Zone and Reckless.

ONE BODY

When whitewater guide Dani Whalen discovers the body of a close friend in the Colorado rapids, she refuses to believe it was an accident. Trey had a wife and son - there's no way he would take risks.

ONE WITNESS

Dani's suspicions are confirmed when a witness claims Trey wasn't alone that day. But before she can find out more, he too dies violently. She takes her evidence to the local police chief, who insists the case is closed. Dani threatens to go public with her suspicions and finds herself thrown in jail.

ONE THING TO KILL FOR

Her godfather, ex-detective Ty Hauck, immediately goes to her rescue. He and Dani visit Trey's hometown - a place that is controlled by an energy company. But in a region ravaged by drought, there's only one resource more valuable than oil - and it's worth killing for.
