Lost Worlds draws together John Howe's incredible artwork with a wealth of historical facts and mythological texts to create a visually stunning, classic title. This unique children's book is a first for John Howe. It is a project which fascinates him entirely, so much so that this is the first subject he has committed himself to write about.

Calum Challenger is a boy with a mission: to track down supposedly mythological creatures and capture their DNA. But while Calum and his friends want to save these beings, an aggressive pharmaceutical company wants to wipe them out.

In this fast-paced, high-tech story, Calum and a group of misfit mates - a computer hacker, a freerunner, an ex-marine and a girl with a very big chip on her shoulder - criss-cross the globe, desperately trying to stay one step ahead of their enemy.
