I'm having a hard time deciding. I've rejected only two titles out of hand and I'd be happy to read any of the contenders. Which to support?
Just as an aside, I like that all of the nominees seem to range from cheap to free*, as former freebies or gettable via KU/KOLL, pd, or OverDrive. It means that cost issues shouldn't keep most from participating. I've already got one each from OverDrive and KOLL and holds on others.
