Girl giant and the monkey king

"Eleven-year-old Thom Ngho is keeping a secret: she's strong. Like suuuuper strong. Freakishly strong. And it's making it impossible for her to fit in at her new middle school. In a desperate bid to get rid of her super strength, Thom makes a deal with the Monkey King, a powerful deity and legendary trickster she accidentally released from his 500-year prison sentence. Thom agrees to help the Monkey King get back his magical staff if he'll take away her strength. Soon Thom is swept up in an ancient and fantastical world in where demons, dragons, and Jade princesses actually exist. But she quickly discovers that magic can't cure everything, and dealing with the trickster god might be more trouble than it's worth"--Provided by publisher.
