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 onto 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, with 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.

All her life, everyone has tried to protect Lady Ella Myerston from the realities of the world. But she knows very well how the dangerous Fire Eyes diamonds have haunted her brother and their friends, and she won't wait for peril to strike again. She intends to take action...and if that happens to involve an adventurous trip to the Cotswolds, then so much the better. Lord James Cayton has already broken two hearts, and now he's determined to live a better life. He does his best to remove the intriguing Lady Ella from danger, but the stubborn girl won't budge.
