After countless heartbreaks, Ciara Reilly has sworn off falling in love and turned her youth, beauty, and unlucky streak of dead-end relationships into a way to make money. After joining the Sugar Girl app, she has climbed the ranks to become one of the few Platinum Girls in Dublin and now has her choice of wealthy clients. It is a way of life for Ciara and means she can keep her family out of debt. The financial perks coupled with the casual dating arrangements suit her, primarily because she learned the hard way that falling in love and sugaring do not mix.

That's until she meets the stunning and wildly fascinating entrepreneur Charlie Keller. Their connection is instant but complicated. Charlie is everything Ciara has ever wanted, but falling for her means giving up everything she already has. Forced to choose between coming clean about her lucrative career or losing Charlie forever, will Ciara go sugar-free? Or will the secrets Charlie is keeping from her result in another heartbreak?
