Literary agent Catherine Gainsborough—a staunch loner—never thought she would change her familiar way of life. But everything changes when, at a literary conference, she meets her former classmate, Melanie.
Shining with happiness, Melanie tells Catherine about the services of a closed agency that matches clients with a partner capable of fulfilling any of their desires. At first, Catherine is outraged by the very idea of such a “service.” However, in the end, curiosity gets the better of her—she accepts her friend’s invitation to join this mysterious organization.
