When a butterfly startles a young rabbit, and the rabbit makes a horse rear, it starts a chain of events, over the course of one day, that will change people's lives . . . and end people's lives. From the climber on Everest to the boy in Malawi . . . the commercial pilot to the American psycho . . . the chaos knows no bounds.

`'. . . action-packed crackers kids will fly through.'' The Sun `'Thrilling and thoughtful stuff for a 21st-century reader'' Telegraph `'A pacy and thrilling read building to a dramatic finale. An imaginative page turner'' Booktrust `'Slick as an oil-spill, and equally combustive, this yarn for mid-teens takes chaos theory as its basis . . . Gripping.'

Non-stop action in this high adrenaline adventure story that is unlike anything published for teenagers before. The concept of chaos theory and the butterfly effect is universally appealing. High-profile author who was the fifth British climber to summit the treacherous North Face of Everest. Exciting and extensive marketing campaign to accompany publication. First of three books which deal with the concept of the butterfly effect, but which are completely standalone adventures. Will appeal to all teenagers, boys and girls. Like '24' in book form . . . the book Jack Bauer would have read as a teenager!

Matt Dickinson is a writer and film maker with an enduring (and sometimes dangerous) passion for wild places and even wilder people. He was trained at the BBC and has subsequently filmed many award winning documentaries for National Geographic television, Discovery Channel and Channel 4. As a director/cameraman he has worked with some of the world's top climbers and adventurers, joining them on their expeditions to the Himalayas and beyond. Along the way he has survived some life threatening dramas; an avalanche in Antarctica, a killer storm on Everest and a night time 'grizzly bear' attack in the Yukon which wasn't quite what it seemed (actually they were beavers!). Matt's proudest moment was filming on the summit of Mount Everest having successfully scaled the treacherous north face of the world's highest peak. www.mattdickinson.com
