If you liked The Rats, then you will like this one, as it is more of the same, except this time the rats are on the rampage in a forest just outside London. (This is the second part of a trilogy, although the books can be read separately.) No-one does this quite like Herbert: The action is taut, the description is vivid, and the story is gripping. If the characterisation is a little one dimensional and the story a bit predictable, it doesn't ruin the enjoyment of the book. Come to it with average expectations and enjoy. Not his best but a good one nevertheless.
