I remember not to long ago reading an excerpt of a book that had either a succubus/incubus (can't remember which) in the family...lol

Anyway in the exceprt, a little girl fell and hurt herself and the succubus/incubus helps her out and then her grandmother or something comes and gets her and tells her to stay away from the guy...something like that.

Anyway I am pretty sure it was an ebook and I remember reading it before Christmas? Anyway it is stuck in my head and I can't get it out of there.

Anyone have any ideas? Please help me!
