Francesca Hartwell adores cats of every kind. Lions, leopards, tigers. And they all love her. Good thing she gets to see them every day, since her father is their caregiver in the Tower of London's Royal Menagerie. She'd love to find a man with whom she could share her love of animals, but so far, no one has stolen her heart. And there's the added snag that whoever she marries must not have anything to do with nobility, as her mother had left her and her father for an earl.

John Fairgate has three rules given to him by his uncle. Inherit the title of baron upon his uncle's death. Give up ornithology. And marry a childhood acquaintance. The first two, John will abide by, but won't like. But the third, marrying a shrew who makes his skin crawl, he simply cannot do. Meeting Miss Francesca Hartwell at the zoo, however, has given him other ideas for a wife. But she's not titled or wealthy. How will he be able to convince his uncle that she's the woman of his heart?
