An English war hero must unlock the secrets of an Irish beauty's heart . . . Named for the heather in her native Ireland, Erica Burke is an aspiring botanist whose dearest wish is to travel to far-off locales. So far, she's only made it to England's Lake District. Stranded there by a storm, she finds the last thing she's looking for-dashing English war hero Major Tristan Laurens, the Duke of Rayhnam. An unexpected heir, Tristan is torn between his duties as an intelligence officer and his responsibilities as a duke. A brief return home to set his affairs in order is extended by bad weather and worse news-someone has secret information about his latest mission. Could the culprit be his unconventional Irish guest? He needs to see her journal to be sure, and he'll do what he must to get his hands on it, even stage a wildly inappropriate courtship… Erica wants nothing to do with an English soldier, and guards her journal as closely as she guards her heart. But though she makes Tristan's task infernally difficult, falling in love with her may be all too easy . . . Praise for Susanna Craig A stunning, sensual storyteller . . . evocative prose and richly drawn characters." -New York Times bestselling author Jennifer McQuiston
