I <3 Goodreads. I like categorizing my books and tracking them; it appeals to my unused library degree. Also, much as they suspect, my friends have similar reading tastes.
Here’s my author page on Goodreads. Most of the stories are available via the equally awesome Escape Pod, heh, but there’s also Broad Spectrum (on my Kindle!). Which, let me remind you, is free free free free free.
If you’re not on Goodreads, you should be!
