I wanted to share some of the science fiction that I absolutely adore.
1. Most things by Peter F Hamilton
My favorite trilogy by him is The Void Trilogy. I actually started with the 3rd book not realizing there were previous books, and about a quarter of the way into it, went back and read the first two.
I love his general world building, the far future sci fi, and really interesting concepts. Sometimes he can be a little long winded (Great North Road).
2. A Fire Upon The Deep by Vernor Vinge
The world building - the universe - in this book is just amazing. I fell in love with the aliens, and the rules governing things in this universe.
