In a world where plastic surgery is as popular as a pair of sexy Manolo Blahniks, suburban single mom Jessica Taylor is trying to make it past forty with nothing more than moisturizer and a swipe of mascara. Her glamorous best friend, TV producer Lucy Baldor, has a different idea of aging gracefully. “My body is a temple,” Lucy explains. “I just don’t want it to crumble like St. John the Divine.”

Jess and Lucy’s friendship has weathered the trials of marriage, the births of children, and the transition from itty-bitty bikinis to “Kindest Cut” one-piece suits. Now the women are discovering that midlife crises aren’t just for men—they’re equal-opportunity dilemmas.

To Jess’s dismay, Lucy announces that she’s taken a lover. A very famous lover. Her husband, Dan, is bound to find out (especially after a picture of the amorous duo appears on Page Six of the New York Post), but Lucy’s too wrapped up in the joys of expensive lingerie and romantic retreats to care. Jess finds herself in the midst of her own romantic predicament when, after ten years of silence, her sexy French ex-husband, Jacques, ends up back in her life—and in her bed. Whether navigating bake sales, bicoastal affairs, or bagels-and-Botox parties, these wise and witty women know that their friendship will remain the one true thing they can count on. Well, that and a good push-up bra, of course. And their bond withstands everything—from an orgy in Willie Nelson’s trailer to a reality TV-show bachelor named Boulder.

Funny, brazen, and often poignant, this irresistible novel offers an unexpected and entertaining look at two women’s midlife adventures. From Thai massage to tantric sex, who would have thought forty could be so much fun?
