Catching up on my Scalzi
The Last Colony is the conclusion of the set started by Old Man's War. It is very well done and the best part of it (to me) doesn't have anything to do with interstellar intrigue, plot twists, and some good, meaty Science Fiction...it's more a psychological/sociological aspect. The Jane Sagan character is so perfectly handled, that it took the prize with this book. How would a person "born" in a fully formed body, with pre-set knowledge, skills and abilities - as well as being constantly in mental contact with her comrades - do when leaving the life of a highly designed and enhanced soldier? I won't spoil any of the book for you - just look for those parts and enjoy.
The Android's Dream is not part of the Old Man's War series - but you will see some of the same ideas present. I think from the ending, that Mr. Scalzi is leaving open the possibility of expanding upon this work as well. Heh.
As for Mr. Scalzi - go read his blog, "Whatever". He is an interesting man tobe sure.
