Book 1 of Animorphs. This is a strong middle grade book. Was it well paced, yes. Did it remind me of Power Rangers? Yes. For the length is it worth the read? Still going with a yes on this one. I would say that boys and girls age 10 and up would enjoy this. Also, I would think it does lean more toward a typical boy book with sprinkled in parts that will appeal to girls. It will be interesting as I move into the series, if my opinion on this will change.
