Over the course of five Hollows novels, Harrison has teased and alluded to readers about Rachel Morgan's true heritage. Is she really a witch? What did Trent's father exactly do to her DNA? Why does Ceri never let on about what she knows regarding Rachel's unusual talent in kindling demon magic? How is it related to Trent's research for the elf race? Why do demons gravitate towards her as if they have an ulterior motive? Why? Because they do!
Finally, Harrison lets the cat out of the bag in a big way...but she doesn't give it to us all in one big enchilada. The entire meat of the book is a lead in to what we have been waiting for but we stop a few times, glean more along the way.
