She explained THE TROUBLE WITH VALENTINE'S DAY (as if you didn't know!) Now Rachel Gibson tells all about . . .

SEX . . .

What is it about men anyway? Bad cars, bad jobs, even bad teeth -- nothing convinces them that they can't snare a Size Two Babe with a D-cup chest. And after way too many internet dates with men named "luvstick" and "bigdaddy182," Lucy Rothschild should know.

LIES . . .

But sitting across from her now is "hardluvnman," and he seems different -- sensitive, honest, and hot! He says he's a plumber, while Lucy claims she's a nurse! She's really a mystery writer, dating online while researching her next book. Hey, everyone lies a little, don't they?

AND ONLINE DATING . . .

But Quinn's really an undercover cop hunting down a serial killer, and he sees Lucy as his top suspect. And while he could really go for this smart, sexy woman with the killer bod -- if that's the only thing "killer" about her -- he knows he needs to wine and dine her and discover the truth. Hey, he realizes the dating scene can be deadly -- but this is ridiculous!
