Lets see... I listen to audio books at work, and I go through one or two a week, it can get hard to remember them all...
Law of the Nines by Terry Goodkind... you should probably avoid this one unless you're a die hard fan of his. The blurb about the book doesn't mention it, but it is tied to the Sword of Truth series, except it's in our world. It's hard for me to say if it has spoilers of the other series in it, since I've read it too, but I don't think it does. If you haven't read the sword of truth books, I think you'll just be confused by this one a bit. Anyways, it's got all of the things I don't like about Goodkind in it, long winded characters, unnecessary repetition and explanations, it's like he thinks we're too dumb to remember what he wrote a few chapters back. And he never misses an opportunity to let us know exactly what his opinions are... cell phones are for idiots, modern art is dumb, and communism is the root of all evil. Goodkind is a good story teller, I suppose, but he's a terrible writer.
I saw some mentions of the Dresden Files, and I'll second them... or third them, whatever. The audio books are especially good. James Marsters is an excellent narrator, I love the way he yells "FUAGO!"
And I have to say this again if you missed it the first time. Read Pirate Latitudes by Michael Crichton. READ IT! This book is great, sea battles, sword fights, and a touch of Crichton sci fi. It's fast paced, and an incredibly fun read, I'm listening to it for the second time already. One of the best books I've read in a long time.
