When a butterfly is trapped in a deserted building 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 runaway in downtown Sydney to the backpacker in South America . . . the pyrotechnics expert to the violent African rebel . . . the chaos knows no bounds.

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

Hannah, homeless and on the run. Gwen and Tehpoe, kidnapped by violent rebels. Todd and Isabella, threatened by piranha attack. Wai Yan, hunted by a cruel dictator. Stian Olberg, fighting to save his vessel from imminent destruction.

For them, and many others, things will never be the same again.

Some will live. Many will die. All are connected.

The action is non-stop in this tense and compelling adventure.

Praise for Mortal Chaos:

'action-packed crackers kids will fly through'

'Thrilling and thoughtful stuff for a 21st-century reader'

'A pacy and thrilling read building to a dramatic finale. An imaginative page turner'
