Books like The Double Wager

What can I say, I'm on a Mary Balogh kick, but this was not one of the great ones. At first it was cute with the tomboy heroine and the bored duke that never smiled, but it quickly turned into foolishness. The heroine turned from endearing to TSTL and ruined any chance of me enjoying the book. The hero and heroine did not really grow as a couple. The second half of the book was too focus on the stupid money lending plot involving the heroine and the duke's cousin. I would have liked to see the leads relationship develop properley without that added plot device.
