House of Suns

Compelling, well thought out, internally consistent and logically sound vision of a fascinating potential future with an interesting take on what it would mean for humanity to continue expanding for millions of years without the ability to travel faster than the speed of light.

Really liked this one, although I felt the ending was a little too open-ended. Maybe he'll choose to keep going with a sequel one day.

I've noticed a lot of other people call this “flawed”, and honestly I can't disagree with them. However, it's so ambitious and executed well enough that I truly feel it deserves 5 stars anyway.

I realize I may differ from a lot of other people in this area, but I don't start at 5 stars and subtract for things I dislike - I start at 0 and add points for awesomeness. By that measure, this is one of the relatively few things I've ever felt that actually deserves a 5.
