The hottest book of the season has to be Stieg Larson's Trilogy. The first in the Series is The Girl with the Dragon Tattoo. One piece of advice, these books are a translation from Sweedish. For some reason it takes to about page 50 before your brain clicks with the translators, but after that hold on to your hat.
James Patterson's Private is about an exclusive private detective agency and a good easy lazy read for Patterson addicts.
I just finished Her Fearful Synmmetry by Audrey Niffenegger. Remember, She wrote Time Travelers Wife, and again she's out there!!
Hope you have time to drop in while you are at the beach!!
