Sybil Sweet has always been lucky, but lately she can't catch a break. After years of bouncing from job to job in search of something that feels right and from man to man in search of something special, Sybil is worried that she's the directionless, floundering daughter her family thinks she is. All she really wants now is a little financial stability and carb comfort. Lucky for her, she's got just enough in the bank to buy a lottery ticket, and the late-night donut store is open.

Kieran Anderson put his dreams of becoming a doctor on hold to take over running his family's bakery, and after fighting a losing battle to save the place, he's exhausted, broke, and no closer to getting back to school. But when a whirlwind of a woman sweeps in late one night, flirty energy gives way to more...until she runs out the next morning, leaving behind her winning lottery ticket.

Lucky for Kieran, his attempt to return the ticket looks like a grand romantic gesture and goes viral, sending sales through the roof. In an effort to keep the store afloat and to convince Sybil's family she can make good relationship choices, they agree to fake a relationship for three months. Even with hundreds of millions of dollars, finding each other might end up being the sweetest bit of luck for both of them.
