The Devil in Winter. Lisa Kleypas (Wallflower Series)

Evangeline Jenner stands to become the wealthiest Wallflower, once her inheritance comes due. Because she must first escape the clutches of her unscrupulous relatives, Evie has approached the rake Viscount St Vincent with a most outrageous proposition: marriage! Sebastian's reputation is so dangerous that thirty seconds alone with him will ruin any maiden's good name. Still, Evie appeared, unchaperoned, on his doorstep to offer her hand. Certainly an aristocrat with a fine eye for beauty could do far worse. But Evie's proposal comes with a condition: no lovemaking after their wedding night. She will never become another of the Viscount's discarded broken hearts - which means Sebastian will have to work harder at his seductions ...or surrender his own heart for the first time in the name of true love.
