"Riordan combines Norse mythology with a number of social issues: gender fluidity, disability, and race and religion. There's some crossover with characters from Riordan's other series, and the ending promises more overlap in future installments. A surefire hit."--Booklist
"The latest installment in Riordan's Nordic-themed fantasy series is a fast-paced adventure narrative featuring snappy dialogue and a diverse cast of well-developed characters. The author possesses a singular talent for re-creating contemporary teenspeak. An entertaining sequel that will whet fans' appetites for the next installment."--Kirkus Reviews
