Like the first book, this is the continuing adventures of Chester and his human Jubal. Still cute, but has fallen a bit flat in the execution of the idea. A bit too neatly wrapped up for my tastes, especially with the extreme danger she put them in in the latter half of the book. (A bunch of cats 'batting around' a fusion weapon to defeat a creature that sucks all the energy from a sun??? I'm sure there will be more books about the pair, the last sentence of the book virtually guarantees it. Still a fine read for tweens and above, especially animal-loving kids. I'll probably read the next one, but it reminds me a lot of her most recent works: the Acorna series, and the Petaybee sequences, neither of which I enjoyed.
