Eurydice Goodenham is convinced that a marriage of convenience with the notorious Sebastian Montgomery, Earl of Rockmorton, would be ideal: in exchange for one child, she can retreat to the library of his country house to write, while he continues his scandalous life in London. But when she finds herself falling in love with her unpredictable, mischievous and secretly honorable husband, does she have any hope of claiming his heart?

Sebastian is bored with the world's amusements, until his friend's ward makes a startling proposal. He can't help but challenge Eurydice's expectations in return. A wild escape to Gretna Green convinces him that his unexpected bride is perfect for him—except that Eurydice doesn't believe in love. Can Sebastian win this bluestocking's reluctant heart in time to save a Christmas—and a marriage—going awry?
