Magnus Chase and the Hammer of Thor

The second Magnus Chase book sends its hero and a new ally — Alex Fierro, a genderfluid child of Loki — on a quest to recover Thor's stolen hammer before a giant uses it to free the imprisoned Loki. Riordan's signature strengths are all present: fast pacing, genuine humor, accurate Norse mythology woven into action sequences, and a warmth toward his characters that makes the ensemble feel like friends. Parents with conservative faith commitments need to know upfront that this book won the Stonewall Award for its portrayal of Alex Fierro, and that gender identity is addressed directly and positively as a theme. A Muslim character navigates her faith alongside Norse mythology in a way that is sympathetic but may raise questions for younger readers. Preview before handing to children under ten; for middle-school readers whose parents are aware, it is a well-crafted adventure.
