Pentacle by William Meikle
I received an E-arc from Darkfuse Publishing in exchange for an honest review.
John is the caretaker in a very special house, it's one where those who have lost someone they love can connect with them through sigils and totems. When he finds an unwelcome presence in the house it is up to him to set things right.
This novella ties in with previous work, Broken Sigils, which unfortunately didn't really work that well for me either. John was a pretty good character and I liked his research on the house through the tapes but the threat wasn't that disturbing to me and I wasn't that interested in it when it was revealed.
Just a case of personal preference and this one just didn't quite work for me to rate it higher.
