He never expected the clues to lead to her…

Edward Adair, heir to the Duke of Boulstridge, is more interested in finding a missing family heirloom than a wife. But when his parents issue an ultimatum – marry or lose your allowance – he reluctantly agrees to attend a house party to find a bride. Instead, he discovers attractive but infuriating Miss Isabella Winthrop in his library, reading the private family journal that holds clues to the location of the heirloom.

Though Isabella finds Edward haughty and arrogant, she offers to take him to the next clue mentioned in the journal if he will pay her, which will enable her to help her brother restore his estate. Edward counters with an offer of an even larger payment…if she agrees to masquerade as his betrothed to deter the other ladies until the house party ends.

As they work together to solve the mystery their mutual attraction grows, but just when they begin to think they should make their engagement real, a secret is revealed that could destroy everything.
