James “Thorny” Thornberg is a brilliant Manhattan tech billionaire who is accustomed to getting exactly what he wants. But when the woman he planned to marry becomes engaged to someone else, he needs the perfect date to make her jealous.

Then he meets Mandy Lane.

Mandy serves coffee at the Stardust Soda Fountain on the Sunset Strip while taking accounting classes at night. Every dollar she earns brings her closer to her dream of sending her twelve-year-old brother, Skip, to an exclusive tennis academy.

Only when Thorny offers to pay Skip’s first-year tuition, Mandy agrees.

Yet there is only one condition.

She must fly to New York, enter Thorny’s glittering world, and pretend to be his girlfriend at his ex’s engagement party.

The rules are simple. Smile. Play the devoted girlfriend. Make his ex jealous. Never forget that their relationship is strictly business.

Yet private jets, glamorous parties, and luxurious nights in Manhattan make it increasingly difficult to remember where the performance ends. Thorny may be gruff, demanding, and determined to reclaim his former girlfriend, but every charged glance between him and Mandy feels dangerously real.

And then Mandy discovers something sinister about the setup that threatens her one chance at happiness ….

Billionaire’s Bet is a fake dating billionaire romance featuring an age gap, grumpy sunshine chemistry, a hardworking waitress, an emotionally guarded billionaire, and a dangerous game neither expected to play.
