Frenemies and Lovers: A Fake-Dating Age-Gap Standalone Romantic Comedy - 40 and Fabulous, #1

Revenge may be sweet, but showing up at your ex's wedding with a hot younger man is even sweeter. Carly has a secret. After a rant about women's empowerment and too much chardonnay, she may have - accidentally? - slept with her frenemy's son. Because the way he played her body was certainly.empowering. But she can't think about that now, not when she must make over her struggling stylist business before she runs out of cash.
The salt in her wound? Now her ex, the one with the iron-clad prenup that left her practically penniless, is marrying his girlfriend. And Carly's invited. Enter Andrew, broken-hearted by the way Carly left him after their one-night stand. He has a problem of his own: though he's the son of tech royalty, his boss won't promote him until he looks like a settled banker. With a steady girlfriend. Andrew proposes a trade: Carly shows up on his arm for a couple of company events, and he'll be her date for her ex's destination wedding.
All business, no sex. That won't be a problem. There's no way she'll fall into bed with a sexy, younger man. Again. Oops. Swoon for this steamy standalone romantic comedy featuring a geeky, cinnamon-roll hero, fake (or is it?) dating, and fabulousness after forty.
