Suddenly Psychic by Elizabeth Hunter

Every woman goes through changes in their forties. Just not… these changes.
Robin Brannon was a normal wife, mom, and antique-shop owner until a brush with death turned her day-to-day life upside down. Now she and her two best friends are seeing things that belong in a fantasy novel. Ghosts. Visions. Omens of doom. Nothing that belongs in the peaceful mountain town they call home.
Added to that, Robin’s marriage is on the rocks, her grandmother’s health is failing, her mother is driving away the customers at her shop, her teenage daughter refuses to get her driver’s license, and her left knee aches every darn morning.
Robin doesn’t have the time, energy, or knees to unearth the secrets buried at the bottom of Glimmer Lake, but fate doesn’t seem to care. Some secrets are just dying to be exposed.
