Morgan Kingsley, Exorcist - Series by Jenna Black
Demons and willing demon hosts are common in this alternative America, but unfortunately so are rogue demons who take unwilling hosts. Morgan Kingsley is an exorcist who gets pulled square into the middle of dangerous demon politics when she's possessed by a rogue demon who happens to be the successor to the demon throne.
Review & Comments
The chemistry between characters in this series continually frustrated me. Most of the characters remain neatly paired off and only have minor romantic difficulties. The promised sexual tension between Morgan and the demons never really materializes.
The pacing can be a bit choppy, both between and within books, although the action is well-plotted.
I would love to see this world fleshed out in additional books.
