I LOVE reading, so I've got a lot of favorites too, but here's a few:

ALL of Terry Goodkind's books. (Sword of Truth series)

The Day of the Triffids by John Wyndham (This was originally published in 1951, but is still an EXCELLENT sci-fi, and they're reprinting it now. I just finished reading my new copy today!)

Deerskin by Robin McKinley (A MUST for dog people!)

And of course, the Harry Potter books.

Oh, and luckies mentioned Tailchaser's Song....WONDERFUL read for cat people!
