Old Man's War

I have to admit, I came to this with a degree of trepidation. I've really enjoyed Scalzi's “lighter” works and wasn't sure I was going to be able to get into his more serious SF. Boy, was I wrong. This was a blast–sure, not as funny as [b:Agent to the Stars 88072 Agent to the Stars John Scalzi http://photo.goodreads.com/books/1303914309s/88072.jpg 15558757] or [b:The Android's Dream 7081 The Android's Dream John Scalzi http://photo.goodreads.com/books/1165606383s/7081.jpg 15558739], but it wasn't supposed to be, it was still a rollicking good time–action, hard SF, and heart (even a couple of laughs)–everything you could ask for.It starts out as sort of an inverse [b:Ender's Game 375802 Ender's Game (Ender's Saga, #1) Orson Scott Card http://photo.goodreads.com/books/1214413570s/375802.jpg 2422333], instead of kids being recruited to fight far-off aliens, we get senior citizens enlisting. Humanity's colonies are spreading through the galaxy and running into all sorts of other species who are trying to do the same, and conflicts ensue. I can't think of much more to say here without major spoilers. Great cast of characters, believable future tech, creepy aliens, intense battles...fun, solid read, really looking forward to the sequel.
