Unraveller is a spell-binding new tale from the Costa-award winning master of YA fantasy Frances Hardinge. In a world where anyone can create a life-destroying curse, only one person has the power to unravel them. Kellen does not fully understand his talent, but helps those transformed maliciously - including Nettle. Recovered from entrapment in bird form, she is now his constant companion, and closest ally. But Kellen has also been cursed, and unless he and Nettle can remove his curse, Kellen is in danger of unravelling everything – and everyone - around him…

Frances Hardinge spent her childhood in a huge old house that inspired her to write strange stories from an early age. She read English at Oxford University, then got a job at a software company. However, by this time a persistent friend had finally managed to bully Frances into sending a few chapters of Fly By Night, her first children's novel, to a publisher. Macmillan made her an immediate offer. The book went on to publish to huge critical acclaim and win the Branford Boase First Novel Award. Known for her beautiful use of language, she has since written many critically acclaimed novels, including A Skinful of Shadows, Verdigris Deep, Cuckoo Song, Deeplight and the Costa Award-winning The Lie Tree.
