What Happened to the Girl Who Was Kept by Someone at a Young Age?

From the back cover

Lucy, 23, ends her three-year arrangement with Mr. Thompson, a wealthy man thirty-one years her senior who kept her in a villa, gave her an unlimited card, and expected her to be ready whenever he wished. She tells him she wants to marry; he stays calm, gives her a generous severance, and she moves out with about $250,000 — enough to live in the city for years, but not enough to settle down.

Raised by a single mother, Lucy had once seen Mr. Thompson as her way to put down roots. Now, with a younger girl already in his life, she understands what she was: an employee who could be replaced. Cindy, the bar manager who taught her how to catch a rich man, warns her that youth is her only capital and that she must marry soon.

Lucy flies to Tasmania, a heart-shaped island far from her past, hoping to escape it. There she meets Jack, a Chinese student finishing his master's in Australia, who finds her the most perfect girlfriend he has ever had.
