Does this book have any relation to the tv series with the same name? I can see a vague connection, especially as far as the personality of the main character goes. It's definitely not a television adaptation of this book, but it has a similar feel that seems to be at least inspired from the book.
chucklesthescot I don't think there is any relation between the two. The title Lost Girl refers to the fact that she hunts for missing girls. I haven't seen the TV series though but in it the mc is a succubus who can kill people.
