The Broken Universe by Paul Melko. It's the sequel to The Walls of the Universe, which I read last month and really enjoyed. Think of a slightly more complex Sliders with young adults, head-to-head pinball, and whether or not you're a 'singleton' or a 'dupe'.
Amazon recommended that one to me recently, and I thought it sounded interesting. Your praise has pushed me over the edge, I'm going to give it a try!
Right now, however, I'm reading You Are Not So Smart
by David McRaney. My first (and at this rate, likely to be only) non-fiction book of the year.
finished Star Wars: Labyrinth of Evil.
Took me way too long to finish reading, partially because of stuff in my life that was keeping me busy, but also partially because it just wasn't grabbing me, which is very unusual for a James Luceno novel. Still enjoyed it way more than Jedi Trial
Up next is Una McCormack's Brinkmanship
