Search in Cup of Joe
(forum waaaaay down there towards the bottom of the page
) and you'll see lots of suggestions in lots of different areas of interest.
I listen to a HUGE variety, everything from Young Adult
(I enjoyed the City of Ember series
) to forensic fiction
(mostly Kathy Reichs, originator of the series
Bones), to non-fiction
(just finished Freakonomics and Superfreakonomics
).
Question: do you live in Vermont? If so, you can get free downloads. PM me and I'll tell you how. If not, do you live in NH? You might be able to get free downloads, depending on where you live. If not, check with your state library system to see if they have a similar service available.
Your local public library is a fantastic source for audiobooks. You can generally get them in either cd or tape form
(my car has both, so I don't care
). They are free, and I find the shelves to be much easier to browse than online.
iTunes also has a HUGE selection of free material. I listen to all the cool NPR shows
(Car Talk, Wait, Wait Don't Tell Me, Science Friday, Living on Earth, etc.
). They have a whole iUniversity or something with whole classes or just talks about interesting things. You can, of course, also pay to get more.
Another free resource for classics is the Gutenberg Project and Librivox. I just finished Wizard of Oz in prep for Wicked and Son of a Witch, which I got from my library. There's also Podiobooks.com. The quality isn't as good as paid sources, so choose carefully.
Finally, if you desperately want to pay for them, check out audible.com. Just plug in whatever you've already read and enjoyed, then start following "if you liked this" links. You can also do that at BN.com or Amazon.com for ideas.
