First novel of a space opera saga with themes of terraforming and time travel in which the hero gets trapped in the future by the edicts of the Chronologic Patrol who police any potential causality breaking time travel.
This book is OK but not great. If high Sci Fi is all about Big ideas and low Sci Fi is all about action packed space adventure then this book tries to do both but doesn't succeed brilliantly at either. Allen does have two "big ideas" in the book but neither is very well thought out and it is easy to pick holes in the way Allen handles them. The novel fares better as a low SF adventure in space but is still a bit slow moving. I'm not rushing out to but the sequel but if I stumble across it I'll probably pick it up to see how the plot develops.
