My Brother's Bride (Serendipity Book 2)

Miss Abigail Nash is no stranger to loneliness. Her mother died giving birth to her, her father's business dealings took him away more often than not, and her ailing great-aunt, unable to provide much in the way of companionship, was a lack-luster guardian at best. When her dear friends offer to launch her into London society, her life takes a turn for the better. An instant success, with suitors, social engagements, and offers aplenty, it seems Abby will at last settle into the life of her dreams.
But appearances aren't always what they seem, and dreams often become disappointments.
Just months into her marriage with a proclaimed darling of the ton, Abby finds herself widowed, penniless, and increasing. Even more precarious are the feelings she’s developing for a man she shouldn’t love, a man the law prohibits her from marrying—her late husband’s brother, the Marquess of Brigston.
