A Midsummer Kiss. Kiss the Wallflower, #1

Orphaned at a tender age, Miss Louise Grant spent her life in servitude to care for her younger siblings. Now, no longer needed as a duchess' companion, Louise has procured employment in York. But on her last night in London, her reputation is shattered when the drunk and disorderly Marquess mistakes Louise's room for his lover's. Luke, the Marquess Graham is determined to never torment himself again by daring to love.
Stumbling into Miss Louise Grant's room destroys his days of bachelorhood when he is pressured into marrying her. However, the cold and distant Marquess knows they'll never have a happy marriage; his new and fetching wife will never crack the protective barrier around his heart. Trying to make the best of a bad marriage Louise attempts to break through the icy visage of the Marquess. But when misfortune strikes and Luke reverts to his cold, distant former self, Louise is not willing to give up on the possibility of love.
After all, ice will melt when surrounded by warmth.
