Venus Prime 1 *** : Better than I expected and an enjoyable end to my sci-fi reading blitzkrieg while on vacation in Costa Rica.

To Sail Beyond the Sunset ** : Heinlein is either a genius provocateur or just a dirty old man. Either way, this book didn't take for me.

Revolt in 2100 *** : Classic Heinlein space opera pulp fiction. Overly simplistic and unrealistic solutions to social problems, but it's fun reading.
