Mutant 59: The Plastic Eaters was one of my favorite sci-fi novels in high school. The one problem you get when re-reading your favorite books years later is that you often notice some glaring plotholes. There's a pretty big one in this story, but I'm not going to go into details. It doesn't necessarily detract from the drama of the story, but it puts into question the genesis of the problem.This book has some good characterization, given the stereotypes that the characters really are. But it's an enjoyable book, with a little more action than The Andromeda Strain, at least on the part of the main characters. FYI: The story was also used as the basis for the first episode of the British TV show Doomwatch.
