The second volume of The Underland Chronicles continues the delightful adventures and imaginative world-building of it’s predecessor. Gregor and his sister Boots return unwillingly to the Underland and find themselves drawn into another quest to seek a rat known as the Bane. [Side note: Being the father of a girl the same age as Boots makes me love her characterization all the more]. The book builds on the Underland with new characters and new locations but at it’s best it develops continuing relationships, especially between Gregor and his bonded bat Aries. It is also a darker story as Gregor faces a tragic loss and must make a difficult moral decision that defines his character. If I have one quibble it is how these stories are guided by prophecies, although there is the counterpoint that the interpretation of these prophecies is often way off base within the story itself. Another excellent work by Suzanne Collins, go get it now!
