His Unsuspecting Heart — Aileen Fish

When Lord Giles' grandmother sends him on a fool's errand requiring him to gain entry into her former home, he strikes up a friendship with the daughter of the new resident, Miss Tabitha Minnet.

Tabby's search for a husband has brought her, along with every other lady of marriageable age, to London for the Season. She isn't particular about titles and income, as long as her future husband is kind, honest, and an excellent kisser. The one she's particularly interested in happens to be the brother-in-law of her dearest friend. Lord Giles is quite the catch!

A madcap cat and mouse chase ensues as Lord Giles searches for his grandmother's lost treasure while avoiding the young lady his great uncle the Duke of Danby plans for him to wed. The more time he spends with Tabby, the less interest he has in Grandmother's wishes, which has him dangerously close to falling in love. Will he find the treasure before losing his heart to Tabby?
