From Tyson's stateofreview.blogspot.com:
The Left Hand of God by Paul Hoffman. This book's been getting a lot of buzz lately and the more I hear, the more I like.
The Gone Away World by Nick Harkaway. Ever since I heard this book has a combination of mimes and ninjas in a believable scene, I've had this on my To-Buy list.
The Red Wolf Conspiracy by Robert Redick. Another book that's been getting lots of good reviews and which I'm really excited to read.
Ender's Game by Orson Scott Card. I loved the book when I first read this a number of years ago and here's another look at the classic.
From Peter's Ubiquitous-Absence:
Elfsorrow by James Barclay. I own Dawntheif, which is the first in the Chronicles of the Raven and Elfsorrow is a little further down the line in the series. Looks good.
The Book of the New Sun by Gene Wolf. This series is considered one of the best out there and Peter seems to agree.
From Mark's Walker of Worlds:
Cosmopath by Eric Brown. This is the last in the Bengal Station Trilogy and I can't help but be interested in a series Mark gives two 9/10's and a 10/10.
From Ken's Neth Space:
Sleepless by Charlie Huston. Again, I'm always intrigued when someone gives a book a 9/10, but Ken mentions that it breaks genre barriers and I'm even more intrigued.
