Hi. I'm looking for a book (forgot the name and author coz it's been years) which has a storyline like this:
A dark/immortal god (of war I think) kidnaps a baby and gives her to a nanny to be raised in isolation. He visits her only on her birthdays till she's of age. He is extremely powerful. After her 18th birthday she goes to live with him and their romance and dynamics unfold after a few months. It's actually a nice story. I did a search for it extensively, but couldn't find it. Please let me know if you've read something similar (the book name or the author). Thanks a ton!
