William Joyce confirms his capacity for imaginative worldbuilding in the second installment of the Guardians series. E. Aster Bunnymund and the Warrior Eggs at the Earth's Core! expands the cast of characters, and I was sorry that the additional perspective characters took away from our time with North, my favourite character - and I think the most interesting - character from Book One. Despite this, I am thoroughly enjoying this children's series, which would be absolutely delightful to read aloud with the family or a class.
