My Immortal by Erin McCarthy

This book was a historical/paranormal romance with the feel of The Twilight Zone/Tales From The Crypt. The story goes back and forth between the present and the past (circa 1790, and later the 1830s). This story was interesting for a few reasons. dotted throughout the narrative were letters from an important character in the hero's past. The heroine had a few things in common with that character. There were a lot of religious and moral questions because the story was dealing with demons and the concept of sin. I thought the book dealt w/ these subjects on more of a "horror" level than the way they are typically treated in regular paranormal romances. The demons themselves were very complex especially the character Rosa. The hero & heroine were also very complex w/ great chemistry and you really felt their inner struggle with deciding what "the right thing to do" is.
