Twilight robbery - Frances Hardinge

Mosca Mye and Eponymous Clent are in trouble again. Escaping disaster by the skin of their teeth, they find refuge in Toll, the strange gateway town where visitors may neither enter nor leave without paying a price. By day, the city is well-mannered and orderly; by night, it's the haunt of rogues and villains. Wherever there's a plot, there's sure to be treachery, and wherever there's treachery, there's sure to be trouble - and where there's trouble, Clent, Mosca and the web-footed apocalypse Saracen can't be far behind. But as past deeds catch up with them and old enemies appear, it looks as if this time there's no way out . . .

Frances Hardinge spent a large part of 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, a few years later a persistent friend 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. She has since written many highly acclaimed children's novels including, Fly By Night's sequel, Twilight Robbery, as well as the Carnegie shortlisted Cuckoo Song and the Costa Book of the Year winner, The Lie Tree.
