The Wrath of the Wallflower — Louisa Cornell

When Lady Alice Lister's first season ends in her shooting her suitor, and her second season ends in complete humiliation, her third season becomes a mission for revenge. But revenge comes at a price, and her handsome accomplice, Sinjin Perriton, is a temptation that may cost her not only her revenge, but also her heart. Sinjin Perriton's shy nature has made his years long correspondence with Lady Alice Lister the closest and most precious friendship of his life. When she asks his help in her plotted vengeance he readily agrees, too readily.
