Making Her His: A Singular Obsession, Book One - Lucy Leroux
I liked this story. I know some people think that it is weird or gross for step siblings to get together, but I am glad these step siblings didn't grow up together, otherwise that might have felt a little strange. I did think that Alex was a bit too controlling at times in the way he went about trying to make sure Elynn was safe, but he did it with good intentions. Even with all his planning and control Elynn was still in danger and Alex didn't even see it coming.
This really is a good romance story and I would recommend it.
