The Manic Pixie Dream Girl SEX Murders?

There's an author's voice in The Manic Pixie Dream Girl Murders that is strong and consistent.  A tone that I seem to be tapping into. 

I really like it.

I always have a honeymoon phase when I'm writing a book; otherwise, I probably couldn't complete them.

This is an unusual book for me.  There is quite a bit of sex, with four letter words that I don't think I've used much, if at all, in anything else I've written.  But the book is about a succubus, and it seems to me to be essential that I explore that.  It doesn't seem out of place.  It's not being done out of sensationalism.  In essence, the action sequences in the book -- where ordinarily I might have a gunfight or a swordfight -- are sex sequences that ends badly.

So I'm struggling with the title.  The Manic Pixie Dream Girl Murders doesn't seem to give the right clue.  I thought about using Blood of the Succubus.  I could use the latter as a sub-title, but it seems awkward.

I've thought of The Manic Pixie Dream Girl Sex Murders, or perhaps The Case of the Manic Pixie Dream Girls: The Sex Murders (or perhaps the Succubus Murders.)

I don't want to promise too much sex either. This isn't porn.

Oh, well.  I have time to think about it.

But it all once again shows me that books have their own needs.  This is the book.  That the content may be awkward doesn't matter.  It's what it is.
