Guilty Pleasure: 23

BattleTech books. I tried playing one of the computer games back in the day, but I do not have attention span for that. But I read quite a few of the books in middleschool (half the school's sci-fi collection was BattleTech or RoboTech, I think the librarian figured it filled the niche and was easy to get more just like it). I ran across book one of the Jade Phoenix trilogy for $1, and it awakened the hunger.

Time to read book 2 (thanks to paperbackswap.com)
