My kids loved the first book in this series, which I picked up at a Scholastic Book Fair, and I was so excited when I saw the chance to read the second one. They were too! The book stands alone, so kids who haven't read the first will do fine reading it. But it also continues to develop the relationship between Shelby and Watson nicely. The parallels to the original story are very fun, but one doesn't need to know anything about the original to enjoy it. All around very fun. I hope there are more!
