Yes? Kind of?

Been playing a game with myself to get me out of a reading rut. I buy books based on their spine color in the order of the rainbow. I go into the used book store, scan for whatever color I'm on, pick out the first 4 books I see and buy the one that sounds the best. If I like the sound of more than one of them I'll do as you do and skip a couple chapters in and read a paragraph or two to get a feel for the author's style to help me pick.

I will be honest and say I've still ended up with some real duds / dnf's. But I've also stumbled across some great books I'd never have picked up otherwise which let me add to my list of "favorite authors" and thus expand my reading repertoire.
