The Great Fox Illusion by Justyn Edwards

Thirteen-year-old Flick Lions has won a place on a new television show, in which young people compete to win the legacy of the Great Fox, one of the world's most famous magicians. But Flick isn't interested in uncovering the Great Fox's tired old magic tricks - she's after something much more important. The magician destroyed her family, and this is Flick's only chance to put things right.
