'The Butterfly Effect ': the scientific theory that a single occurrence, no matter how small, can change the course of the universe forever.

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 a climber on Everest to a boy in Malawi . . . from a commercial pilot to an American psycho . . . the chaos knows no bounds.

This heart-stopping adventure by writer, film maker and climber Matt Dickinson will leave readers breathless. It's the book Jack Bauer would have read as a teenager!
