When a Duchess Says I Do — Grace Burrowes

Duncan Wentworth tried his hand at rescuing a damsel in distress once long ago, and he's vowed he'll never make that mistake again. Nonetheless, when he comes across Matilda Wakefield in the poacher-infested and far-from-enchanted woods of his estate, decency compels him to offer aid to a lady fallen on hard times. Matilda is whip-smart, she can read Duncan's horrible penmanship, and when she wears his reading glasses, all Duncan can think about is naughty Latin poetry.

Matilda cannot entrust her secrets to Duncan without embroiling him in the problems that sent her fleeing from London, but neither can she ignore a man who's honorable, a brilliant chess player, and maddeningly kissable. She needs to stay one step ahead of the enemies pursuing her, though she longs to fall into Duncan's arms. Duncan swears he has traded in his shining armor for a country gentleman's muddy boots, but to win the fair maid, he'll have to ride into battle one more time.
