Lady Jane Cummings is certain that her summer is ruined when she is forced to reside at isolated Merrymere Lake with her reckless brother and ailing father. Her fast-paced London society is replaced with a small town grapevine. But one bit of gossip catches Jane's attention--rumors that the lake's brooding new resident is also an elusive highwayman.

Jane must face the much-discussed mysterioso after he saves her brother from a pub brawl. She immediately recognizes him from London: Byrne Worth, war hero and apparent hermit--whom she finds strangely charming. The two build a fast friendship, and soon nothing can keep this Lady away from Merrymere's most wanted. Convinced of his innocence, Jane is determined to clear Byrne's name--and maybe have a little fun this summer after all.
