Currently reading The End of Temperance Dare by Wendy Webb (she's a 25 year family friend of my father's so I got her book for free ). Some of my favorites, however, are John Sanford's Prey series. A Child Called It by Dave Pelzer of course, and I really liked Micro by Michael Chrichton.
I'm kind of very much in to the Crime/Sci-Fi genre if you couldn't tell.
