The Poptropica series is based on an on-line role-playing adventure game imagined by Jeff Kinney. In this book Oliver, Mya, and Jorge are on a hot air balloon ride that crashes on an unknown island. They soon realize the island is filled with Vikings and the balloon’s pilot has a sinister reason for bringing them there.
The graphics are bright and the story is fast-paced and exciting. There are four books in the series. Reading the books may encourage kids to check out the game or vice versa, but, it isn’t necessary to play the game to enjoy the book.
The book was fun, but will appeal more to kids than adults.
