Maggie knows something s off about Val, her mom s new husband. Val is from Oldworld, where they still use magic, and he won t have any tech in his office-shed behind the house. But more importantly what are the huge, horrible, jagged, jumpy shadows following him around? Magic is illegal in Newworld, which is all about science. The magic-carrying gene was disabled two generations ago, back when Maggie s great-grandmother was a notable magician. But that was a long time ago. Then Maggie meets Casimir, the most beautiful boy she has ever seen. He s from Oldworld too and he s heard of Maggie s stepfather, and has a guess about Val s shadows. Maggie doesn t want to know... until earth-shattering events force her to depend on Val and his shadows. And perhaps on her own heritage.
