Suggestions from a former bookstore manager:
Stay away from newer Dean Koontz, although Intensity was quite good
H.P. Lovecraft (author) "Twilight Zone" older, pulp-horror type stuff, but not cheesey
The Historian by Elizabeth Kostova PHENOMENAL Everything you want in a vampire book and everything you want a Dan Brown bok to be (ie it's a page turner but has significant character development w/ detailed, thorough description)
Neal Stephenson (author) Cryptonomicon: fantastic code-breaking thriller set during WWII and present day. Lots of science & heavy math, but you don't need to have a degree in either to think it's a great book.
If you just want a fun book that's throught provoking and funny, deals with family dysfunction in a beautiful way, I would recommend either of the Mark Haddon books (The Curious Incident of the Dog in the Nighttime and A Spot of Bother). Haddon is a former poet who uses a perfect paucity of words to get across his point.
If you like kind of Blair Witch-style spooky books, Mark Danielewski is good (his sister is the singer/songwriter Poe).
If you're a bit of a Gen Xer Douglas Coupland rings true to a lot of late 20 to early 30-somethings.
Some cheesier Vampire books, but quick, fun reads are those by Laurell K Hamilton. Stay away from the Meredith Gentry series by Hamilton, though. Not fun reads, in my opinion.
Also, sign up for Borders rewards at www.bordersstores.com. They'll send you great coupons & no spam.
Happy reading!
