Book 1 of Megamorphs from the Animorphs series. This was interesting as all the characters got their own chapter. Aside from that it is all the action you have come to enjoy. It was interesting to read this novel as it actually takes place mid series of Animorphs and the author kept the tension high even though you knew that it could not significantly affect the main series. If you like the series, this is a fun chance to go back and revisit those characters.
