"Don't look at him, dear. He's dangerous." Isabella Bankmill seeks a husband whose character matches her list of requirements. The man must share her faith, but he must also possess a certain je ne sais quoi. The enigmatical Lord Gregory Gordon Bromby--London's newest literary sensation--certainly possesses the latter. Despite a deformed foot and alarming views on politics and religion, he attracts the ladies in droves.

Haunted by his past and overwhelmed by his newfound celebrity status, Lord Bromby's obsession with his own doom leads to reckless behavior. When he is stalked by an obsessive aristocrat seeking an elopement, Bromby's friends urge him to marry a suitable lady as soon as possible. Intrigued by Isabella's convictions, and hoping to avoid further scandal, Bromby proposes to Isabella.

Isabella also receives an offer of marriage from kind-hearted philanthropist, David Beringer--a man equally devoted to his faith--but she only has eyes for Lord Bromby. Blinded by his talent and good looks, Isabella convinces herself that he's not as dangerous as everyone claims. But when Bromby's world violently collides with hers, Isabella must decide once and for all who is lord of her life. God or Bromby?
