Tamora Pierce might just be the queen of fantasy young adult novels. Trickster's Choice takes place in the Copper Isles, which are ruled by an incompetent king with hedonistic and power-hungry heirs. It's a society where lighter skinned populations hold more power. The novel's lead, Aly, is an aspiring spy. When she leaves home, she gets captured by pirates, becomes enslaved, and fights to survive within the society's values.
