Someone to Romance by Mary Balogh

Love comes when you least expect it in this captivating new novel in the Westcott Regency romance series from the bestselling author Mary Balogh.

Lady Jessica Archer lost interest in the glittering excitement of romance after her cousin and dearest friend, Abigail, was rejected by the ton when her father was revealed to be a bigamist. Now that she is twenty-five, however, Jessica decides it is time to wed. Though she no longer believes she will find true love, she is still very eligible. She is, after all, the sister of Avery Archer, Duke of Netherby.

Jessica considers the many qualified gentlemen who court her. But then she meets the mysterious Gabriel Thorne, who has returned to England from the New World to claim an equally mysterious inheritance. Jessica considers him completely unsuitable, especially when, while they are still barely acquainted, he announces his intention to wed her.
When Jessica guesses who Gabriel really is, however, and watches the lengths to which he will go in order to protect those who rely upon him, she is drawn to his cause–and to the man.
