I started out not vibing with the 4th book in this series and it ended up being my second fave. The development of the lore and hints at further events expands well in this book. Naomi is our French ballet dancer ghost who never apologizes for who she is and its a delightful twist on the typical shy timid heroine. The fact that each female character always goes to another woman for help first is awesome and I'm loving the development of female friendship.
