Sparks fly and passion ignites between two reluctant lovers who must overcome the pain of their pasts to find happiness in this enchanting novel in New York Times bestselling author Lisa Kleypas' wildly popular Hathaway series

Hired as a companion to the Hathaway sisters, Catherine Marks has built a new life for herself, away from her dark past. She adores her delightful charges, and the lively Hathaway household is the closest Cat has ever had to a family of her own. Everything is perfect--except for Leo Hathaway, the girls' charming and utterly exasperating older brother who drives her to distraction. But when their heated sparring explodes in a sudden kiss, Cat can no longer deny the powerful attraction between them--or the thrill she feels when Leo makes her a shocking proposition.

To save his family home, Leo must marry and produce an heir. The reformed rake vowed he'd never love again after tragedy shattered his heart. Yet the prim and proper Cat challenges him in surprising ways, and her beauty and prim demeanor fuels a desire he cannot control. When the secrets Cat has tried to outrun threatens to separate them forever, Leo and Cat must find a way to banish the ghosts of the past to build a future together.
