The Nature of a Lady by Roseanna M. White

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 all: love.

All Libby wants to do is to be allowed to study nature.  Not be a society lady.  Her brother has arranged a marriage for her with his best friend.  The problem is that they argue any time they're together.  She refuses to marry him.  She convinces her mother to let her stay at a cottage in Scilly for the summer.  She soon discovers that she is staying in a cottage that had previously been rented by someone else named Elizabeth.  Only they disappeared and people think she's that Elizabeth.  She meets Oliver, the brother of the missing Elizabeth.  She soon discovers that he loves nature just as much as she does.

The only negative I can say about this book is that sometimes it went into too much detail about the bugs Libby was studying.  Other than that, it was a good book. A little bit of mystery and a little bit of romance.

I received a copy of this books from Bethany House Publishing via NetGalley in exchange for an hones review.  I was not compensated in any way.
