Cover ArtI like adventure stories. This one is about a girl in Nigeria who discovers she has special powers and finds herself and her friends who also have powers having to use them when there is a ritual killer on the loose. The sequel is also good, but it was a little scarier than the first one at points so maybe wait until you are older to read that one.
 
Publisher Description:
Twelve-year-old Sunny lives in Nigeria, but she was born American. Her features are African, but she's albino. She's a terrific athlete, but can't go out into the sun to play soccer. There seems to be no place where she fits in. And then she discovers something amazing--she is a "free agent" with latent magical power. Soon she's part of a quartet of magic students, studying the visible and invisible, learning to change reality. But will it be enough to help them when they are asked to catch a career criminal who knows magic too?
