Thanks to all who commented on the summery. I made some changes. How's this?

Ghost Mountain is a paranormal cozy set in the Black Hills of South Dakota.

Cerridwen “Cerri” Baker, named after a long-forgotten Celtic goddess, is 36 years old and the mother of three. She has spent her entire life trying to fit in by not following the mystical, wise woman path her mother and sister embrace. But when her husband’s job forces the family to move to South Dakota, Cerri starts getting information from her Lakota spirit guide about a murder at a Native American holy site — Devil’s Tower.

Calling in an anonymous tip to the FBI makes her a suspect in the murder, and now she must convince the arrogant and suspicious Special Agent Joseph Oliver that she isn’t involved.

As Cerri struggles to balance her desire for normalcy with her spirit-driven destiny to help those who can’t help themselves, she finds herself at the mercy of Agent Oliver — as well as a killer protecting a deadly secret.
