Kindred Spirits - Jean Marie Bauhaus

Ghosts don't scare Chris Wilson.
Murderers do.

When a haunting investigation turns into a cold case revival, Chris is thrust into the most dangerous work of her career. Jimmy Brandt, a teenage ghost trapped in his brother's house, wants one thing: the truth. He was killed, and his murderer walked away clean.

Chris and her ghost sister, Ron, agree to help him-whether Jimmy's brother is ready or not.

Derek Brandt built a career tearing apart the paranormal, not partnering with it. But when objects fly through his kitchen and his dead brother starts communicating through a medium he once publicly mocked, Derek has no choice but to face the impossible... and confront a past he's tried for years to escape.

As Chris and Derek reluctantly join forces, their investigation uncovers buried evidence, dangerous leads, and a connection between them neither expected. But their search also triggers something they didn't foresee:

The person who killed Jimmy has noticed.

Now a medium, her ghostly sister, and a hardened skeptic must solve a murder with a killer who's still at large-and watching their every move.

Some hauntings start with unfinished business.
This one ends with a fight for the living.
