A bonus scene featuring Morgan Tremayne, the brother of Oliver and Beth Tremayne of The Secrets of the Isles series.

1906 Lady Elizabeth "Libby" Sinclair, with her love of microscopes and nature, isn't favored in society. She flees to the beautiful Isles of Scilly for the summer and stumbles into the dangerous secrets left behind by her holiday cottage's former occupant, also named Elizabeth, who mysteriously vanished. Oliver Tremayne—gentleman and clergyman—is determined to discover what happened to his sister, and he's happy to accept the help of the girl now living in what should have been Beth's summer cottage . . . especially when he realizes it's the curious young lady he met briefly two years ago, who shares his love of botany and biology. But the hunt for his sister involves far more than nature walks, and he can't quite believe all the secrets Beth had been keeping from him. As Libby and Oliver work together, they find ancient legends, pirate wrecks, betrayal, and the most mysterious phenomenon of love.

Beth Tremayne has always been drawn to adventure. During her childhood, she fed that desire by exploring every inch of the Isles of Scilly. As an adolescent, she dreamed of love in London's ballrooms. Now, stumbling across an old map on her family's property, she's found more adventure than she ever craved in the hunt for pirate treasure. Unfortunately, Beth can't escape the attentions of her family's guest, Lord Sheridan. Sheridan has spent years pursuing whatever archaeological interests caught his imagination. And when he discovers that Beth's search connects with one of his favorite pirates of history, he can't help getting involved. Plus, he finds her irresistible, even though she insists he stole a prized possession of hers. As they work together following different clues and drawing closer to danger, they start to piece together a story of tragic love and piratical adventure. But the true surprise is the treasure they discover in each other.

After a summer of successful pirate-treasure hunting, Lady Emily Scofield and her friends must hide the unprecedented discoveries they've made, thanks to the betrayal of her own family. Horrified by her brother, who stops at nothing to prove himself to their greedy father, Emily is forced to take a stand against her family—even when it means being cut off entirely. Bram Sinclair, Earl of Telford, is fascinated with tales of King Arthur and the Knights of the Round Table—an interest he's kept mostly hidden for the last decade. But when a diary is unearthed on the islands that could lead to a secret artifact, Bram is the only one able to piece the legends together. As Bram and Emily seek out the whereabouts of the hidden artifact, they must dodge her family and a team of archeologists. In a race against time, it is up to them to decide what makes a hero worthy of legend. Is it fighting valiantly to claim the treasure . . . or sacrificing everything in the name of selfless love?
