After the experimental "Matrix," Perry & Tucker return to more normal Doctor Who territory with "Storm Harvest." Doctor 7 and Ace go on holiday to beach resort planet Coralee. What could go wrong? Well, apparently there was once an ancient civilization there that built a nearly indestructible bio-weapon called the Krill. No, not the tiny shrimp-things that whales eat. This Krill are individual mechanisms of pure destruction that cannot be reasoned with. It turns out that a race of rugby-player sized humanoids called the Cythosi have somehow learned about these Krill and want to reactivate them to use in their own war. The first two parts of the novel are the exploration parts, where The Doctor and Ace gradually uncover what is going on. The second two parts are the bloody denouement. It becomes one big gore fest driven by not one, not two, but three mad men (well one a Cythosi, one a dolphin, and one a Cythosi who thinks he's human, or sometimes not), each of whom want more or less total destruction of everyone else. I have some quibbles with some of the basic science that Perry and Tucker really ought to have known about, such as that nuclear reactors do not blow up, and probably in the far future, if they are still using nuclear reactors by then, the likelihood of blowing up would be next to 0. Another is that objects travelling in space do not arc. The novel has a number of interesting bits, and goes a long way toward straightening out the relationship between Doctor 7 and Ace. Still, the ending is too frantic, too desperate.
