The Curse of the Old Woods — Elizabeth Andre

Two rival lesbian paranormal investigators. A dangerous cursed entity. Long dark nights in the old woods.

Maya Nicholas doesn't need any help finding ghosts. They find her and talk to her all the time.
Julie Sussman doesn't need any help either. She solves plenty of cases, both normal and paranormal, without any special abilities.

When they learn that both of them have been hired to find a teenager, lost decades ago in the haunted Promontory Woods, they are not happy. But when they find the teenager's ghost and discover that she, along with many other spirits, are being held captive by an evil entity, they have to work together.

Or they, along with many others, will never leave the woods again.
