Still Into You. A Penguin Special from Berkley

A new, sexy novella from the author of Crash Into You.Seth and Leila used to have trouble keeping their hands off each other. Passion, desire, love-it was all there. Yet, eight years after their whirlwind marriage and kids, they've settled into a life where choosing Letterman over Leno is considered a wild night. Seth knows things need to change. But when he hears his wife call into a relationship radio show and admit she's been tempted to cheat, he realizes how far off course they've gotten.
He comes up with a dramatic plan. Three days. No rings. He'll take Leila to The Ranch, a resort where any sexual fantasy can be had, and give her the freedom to have whatever or whomever she wants. However, Seth doesn't intend to simply stand by and watch other men fulfill Leila's dark desires. He has a lot more bad boy in him than his wife suspects and he knows there's only one man who can give her what she needs.
Now he has to show her why that man is him.
