I'm a big fan of Haiblum's science fiction, but I have to admit that this isn't his best. His style is '50's hard boiled detective fiction, and his characters are not well developed, but the writing is amusing, and I was entertained. His better works are the Interworld series, and The Identity Plunderers. But having said that, I did enjoy reading this, and I've actually read it twice. I get tired of authors who write technically well, but bore the reader. This guy writes to be entertaining, and I think he has a real talent for it. Yet the humor isn't forced, and never interferes with the story. As for what genre this is in, who cares?
