This was an absolutely delightful book in every possible way. Clever, funny, complex without being over-complicated, and page-turning, with hints at worldbuilding that (as usual) I want to know all about ASAP, please and thank you. I would say I haven't been so hooked on a middle grade book in years...if I hadn't read Dragon Pearl two weeks earlier. Between the two of them, I'll definitely be checking out more of the Rick Riordan imprint's catalog.
