Fifty Ways to Leave Your Husband
K.C. Wilder

Well, except that her husband is a serial philanderer, her mother-in-law is the devil in Lily Pulitzer, one of her sons is miserable at prep school while the other is dismissive of her altogether, and it takes a cocktail of antidepressants to get Eve through her day.
When a chance encounter with a hunky stranger coincides with Eve's discovery of her husband's latest betrayal, she throws caution (and at least one perfectly good pair of panties) to the wind. Is she having a crisis inspired by her impending fortieth birthday, or is she just ready to take a long, hard look at her life and shake things up a bit?
Egged on by Tamara, her brash, potty-mouthed best friend, Eve embarks on a steamy adventure with perpetual playboy Finn. Amidst the rich backdrop of coastal Rhode Island, Eve discovers how much of herself she's sacrificed over the years -- and how much more she may have to sacrifice yet to bring passion and meaning back into her life.
