The third book in the Tunnels series, Freefall, is available in the UK. Deeper was published in the US in February 2009, and quickly followed in the footsteps of Tunnels to become a New York Times Bestseller. The series features fourteen-year-old Will Burrows, who life is turned upside down when his father suddenly goes missing. With the help of his friend Chester, Will discovers a tunnel under his house, and it brings him into contact with a hidden city called the Colony, and the terrifying and brutal race of people who rule it. These people are called the Styx, and they want to take control of the surface. If you thought you were safe, you'd better think again.
