Query: Not by Niven and Pournelle

Badly written and unbelievable, this is the worst book to have these two guys' names on it since Footfall. This time Science Fiction FANS save the world. Clearly this was submitted for publication by a fan who attends conventions and Niven and Pournelle decided to capitalize on the fawning adulation of convention kids by helping to get it published. That'd be okay if it was a good story or good writing or a good idea but it's not any of those things. If you like books that suggest that it's important to go to SF conventions and that such people are special because they do, then this book is for you. If you want good fiction in your Science Fiction...stay away.
