Perfect Blood, a
Books in the Hollows series are always compelling. In this latest entry, though, I felt like someone had told the author that she needed to work on the romance angle, so there's a half-hearted, poorly executed push-pull between our heroine, the witch demon and the elf who has been her nemesis since the first book, if I remember correctly. I do like that Rachel's love interests are always flawed, in a way that can't be brushed aside.
