Footfall: A solid, workmanlike alien-invasion & disaster novel
4 stars
A large and well-written novel about an alien invasion and planetary catastrophe. Not top-notch Niven, and his tendency to use confusing polysyllabic alien names gets to be a bit much (as it often does in his work), but it's an exciting and interesting book with sympathetic characters and a well-handled plot.
It does end rather abruptly, though. I liked it better after the third or fourth re-reading.
