Oleander

Eli tried to leave the supernatural life behind. Problem is, it won't let her go.
Eliza "Eli" Moore may have been born a seer, but she didn't want to live like one. That was why she became a private detective, and opened Nine Lives Investigations. Being able to talk to the dead gives her an undeniable edge in solving cases, and she figured it was all for the greater good. Then Eli is forced to exorcise a demon, the local witch elder ends up dead, and Eli fears she's in over her head.
Throughout it all, Eli has one dedicated ally: Dan, a mortal police detective who isn't scared of things that go bump in the night, and who hints he wants to be more than friends. But mortals and seers don't mix...do they?
Before Eli can sort out how she feels about Dan, an enemy from her past resurfaces and threatens everything she holds dear. Eli is forced to take on the title inherited from her grandmother, and become the Mistress of Seers-but just because leading the seer community is her birthright doesn't mean anyone will follow her.
