ghostly shenanigans

Delia Martin is from early twentieth-century San Francisco and she has come back to help care for the woman who took her in when her parents died in the San Francisco fire. She has always had ghosts as companions and originally she ran away to New York to escape their ever-presence, which disconcerted her. Now she's back and there are more around and they seem to be related to the case her foster-sister's fiance is involved with. A serial killer who left for a while and seems to be back to prey on the extra people from the Exhibition that's in San Francisco this year.
It's that pre-war era that is quite interesting for a lot of writers and I liked it. This is a cop drama with some supernatural elements that really appeals to me and keeps me reading. There were moments where the pacing seemed uneven but overall it was an interesting read with people who cared for and about each other throughout. I'm looking forward to more in this series.
