Lonecat bought a copy of Half Blood Prince on the day it was released.
I bought a pile of Sharpe books.
She read it, then read a bit of Phoenix, then read Prince again.
Last night, she loaned me her copy of HBP, and I took it, resolved to only read a few chapters at a time, and promptly devoured a third of it.
I finished it on the bus home this evening, less than 24 hours after I obtained it.
For sale, one resolve, barely used.
