Here are the Young Adult novels under consideration for this year's Locus Award (a list that is the result of a poll of Locus readers)
The Hotel Under the Sand, Kage Baker (Tachyon)
Going Bovine, Libba Bray (Delacorte)
Catching Fire, Suzanne Collins (Scholastic; Scholastic UK)
Liar, Justine Larbalestier (Bloomsbury; Allen & Unwin Australia)
Leviathan, Scott Westerfeld (Simon Pulse; Simon & Schuster UK)
Winners will be presented during the Science Fiction Awards Weekend in Seattle WA, June 25-27, 2010
I wonder if this is the first time a married pair (Larbalestier and Westerfeld) have been nominated in the same category. Looking for more information on this award, I learned that in this case, it's the publisher who gets a certificate, not the author. So perhaps it won't effect their marriage...and I bet it goes to Catching Fire anyway.
And I guess I really do have to read Liar now. I'm surprised that it is sff enough to be on this list...I had the impression that it was pretty straight YA.
