Climbing Mount TBR

I was looking for a new series and I found it. Felix Castro (Fix if you're a friend) is an exorcist in a future London where the ghosts have risen in earnest. Some are your typical haunts, others come back and reanimate their own bodies or those of animals. In this world a loup garrou is an animal animated by a human ghost.

Felix has been taking a sabbatical due to an exorcism that did not go as expected. But a man has to earn money. He takes what looks like a straight forward exorcism to rid a government building of a spectral woman. All he needs to do is get in contact with the ghost enough to release her to wherever ghosts go. But things are not straight forward as expected and unfortunately Felix has both a curiosity problem and a tendency to justice at all costs. His simple exorcism turns up a murder, a thief and a sex trafficking ring, not necessarily in that order.

Felix prevails, not without some damage, and ends up with a succubus as an intern at the end.
