Equal parts memoir, history book, and field guide, The Hedgehog's Dilemma provides an overview of one of the world's quirkiest mammals, as well as Warwick's personal hedgehog-related adventures that have taken him from the UK to China and back.

If you've ever fantasized about going to Mars, you've no doubt thought about how you'd get there, how long it would take, and how you'd survive the planet's frigid temperatures. But you probably never considered things like how to invest your money on Mars, how to have a social life, and where to get a job there. In his new book, How to Live on Mars, Dr. Robert Zubrin moves beyond the idea of humans taking a brief exploratory mission to Mars, and considers what it would take to actually live there. Zubrin is the founder and president of the Mars Society and president of Pioneer Astronautics, an aerospace research and development company in Colorado. Popular Science correspondent Laurie Schmidt recently sat down with Zubrin to discuss his new book and his philosophy about the prospect of humans settling Mars.
