Love Contract by Sophie Lark

Dating Tip #1: Never choose a fake boyfriend too hot to resist...

Theo Mahoney’s culinary dreams sit on the back burner. Hired as a private chef for a billionaire, her boss' eccentric demands never leave her time to cook.

Another soul-destroying workday takes a spicy turn when Sullivan Rivas, a blast from her high school past and old nemesis, springs a blackmail scheme on her. Armed with a secret that could torch her career for good, the devious and unfairly gorgeous Sullivan demands a meeting with her elusive boss.

What was supposed to be an introduction escalates into a full-blown fake romance, complete with double dates and public displays of all-too-real affection. Lines are crossed, promises are broken, and phony dates become genuine feelings, until Theo realizes that the only thing more devastating than getting caught with a fake boyfriend… is falling for him.
