The Dancer From Atlantis

Poul Anderson is a prolific sf author, and most of his books are good. However, he has a tendency to write poor time travel novels. In fact, I've read half a dozen of his time travel stories, and they all suck. So don't read The Dancer From Atlantis. Instead, I suggest Tau Zero or Satan's World. Basically, 9 out of 10 Poul Anderson novels not involving time travel are great novels. But stay away from time travel stories at all costs.
