From the author of the phenomenal bestseller, A BRIEF HISTORY OF TIME. A collaboration with his daughter on his first ever children's book.

"It is like a Dr Who adventure, inspiring curiosity and amazement. It makes a case for the relevance and fascination of physics, and for the importance of scientists and eco-warriors working together to save the planet. With a happy circularity, the plot depends on a recent discovery: Hawking Radiation, the leaking of particles out of black holes until they destroy themselves" The Sunday Times "Gripping, informative and funny" The Bookseller "A true beginner's guide to A Brief History of Time" Publishers Weekly "A delightful book for young readers" Independent "George's Secret Key to the Universe is a novel that anyone who devoured Captain Underpants a year or two ago will appreciate" LA Times
