Hot Flashes and Highballs - Mystic on the Rocks, #1

She never wanted to be special. But when her best friend is possessed, can she master a sudden telepathic power and exorcise a teen spirit? Sam is perfectly happy being normal, thank you. She can't see ghosts or communicate with the dead, and she only recently made peace with their talking cat. But when a gum-smacking teen from the Eighties, possesses a friend's body, she's suddenly thrust into the neon-lit spotlight of a murder mystery with a retro twist.
  Just when she thinks she has a plan to find the killer and set the wise-cracking spirit free, things heat up in more ways than one. Flashes of warmth and unexpected psychic murmurs make for one dreadful investigative cocktail.   Can Sam mix up an aperitif of justice for a ghostly girl lost in time? Hot Flashes and Highballs is the delightful first book in the Mystic on the Rocks midlife paranormal cozy mystery series.
If you like fish out of water, spectral shenanigans, and snark for days, then you'll love Lynn M. Stout's cocktail of adventure.
