Tunnels is a subterranean fiction novel by British authors Roderick Gordon and Brian Williams. It was initially self-published as The Highfield Mole in 2005, and re-released as Tunnels by The Chicken House in 2007. The story follows Will Burrows, a 14-year-old 'archaeologist', who stumbles upon an underground civilization called The Colony. Will and his friend Chester flee The Colony and set out to find Will's father, in the Deeps, a place even deeper in the Earth than The Colony. Tunnels was critically well received, although some complaints about its lengthy, slow start were recorded. The book placed on The New York Times Children's Chapter Books Bestseller List in February and March 2008. It is the first book in the Tunnels series, and was followed by Deeper (2008), Freefall (2009), Closer (2010), Spiral (2011) and Terminal (2013). BBC Audiobooks and Recorded Books have released audio editions. Source: Wikipedia (en)
