A rather patchy and confusing sequel to 'Planet of Evil', a story which stands very strongly by itself in any case. There are far too many characters flying around the scene and their motives are frequently not explained properly, leaving the reader in the dark. The story does not convincingly further the story of Morestra either, though there are a few interesting ideas such as the energy tower, and the story does hot up quite a bit towards the end. It's not a bad story by any means, but nor is it one of the best. Just average, really.
