The Gone Away World by Nick Harkaway

There were whispers of nepotism when this debut novel by John le Carré's son was bought for a reputed £300,000 in 2007. But on reading this magnificent, sprawling, epic work, critics made it clear that it was published on its own merits. Set in a post-apocalyptic world of mostly uninhabitable badlands, this hilarious, action-packed book combines a touching tale of friendship, a thrilling war story, and an all-out kung-fu-infused mission to save the world
