Worth the price? I've found some amazing books by reading Jo's Tor column in recent years. The most recent were Sarah Monette's Melusine, Virtu, and the Mirador, which I would never have thought to pick up because they were published with covers that made them look like romance novels. They're actually very original and incredibly good fantasy novels written in alternating viewpoints between a gay wizard and his lost half-brother, and she hooked me from the opening couple paragraphs. I read the first, reserved the next couple at the library and then was up until 1am the next couple nights finishing the other two. I had a couple miserable exhausted days at work, but I couldn't stop reading them. Another book I tracked down because of her column was Candace Darcy's Black Wine which is like nothing else.
I think my point here is that if you haven't been reading the columns, then hell yeah it's worth the price if it helps you find some books you'd never otherwise read.
