Rebellion drove Mercy Rutherford to Scotland to escape the possessive grip of her fiance. But it’s fate that lands her in the crumbling highlands castle of Lennox Caitheart. A dreamer with visions of inventing airships, he’s most certainly mad. Handsome beyond words, he’s also causing an irresistible flutter in her stomach beyond reason. When Gregory arrives to see their arranged marriage to its bitter end, Mercy desperately turns to Ross with an offer of her fortune–and her hand in marriage.

The Earl of Morton has a reputation for being a daredevil eccentric, but even he is hesitant to engage in such a rash proposition–no matter how utterly beguiled he is by the wildly independent American heiress. And yet, with so much at stake, how can he possibly say no? But when their unconventional union grows into a passionate and inseparable love, more than Gregory’s obsession threatens them. Now, Lennox and Mercy will have to risk more than their hearts to save it.
