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.

Conan Doyle knew how to tell a rattling good adventure yarn and without a doubt so does Andrew Lane. He writes fluidly, introducing his characters with style and humour, never labouring a scene or wasting words; admirable qualities for any author, but in some ways, even more necessary for someone writing for a younger audience
Crime Review
Andrew Lane made all the difference... It's nice to have an author who occasionally indulges us all in wild flights of fantasy
The Guardian Children's Books
This book was great fun to read and I think that it would be a good read for any teenager. It has a strong plot which is full of unexpected twists, turns and developments.
