Self-taught "seer" Shay has much to learn as autumn hits the quaint coastal town of Bray Harbor. Since attempting the art of blending herbs at her popular shop, Crystals & CuriosiTeas, she's set on growing ingredients in the mysterious greenhouse on the second floor—if only she can separate the medicinal plants from the deadly ones. Her new skills are put to the test when she meets pub owner and ex-detective Liam Madigan's Gran. A psychic from Ireland known for interpreting tea leaves and people, Gran encourages Shay to build upon her natural talents and hold her own group reading . . .
Despite Shay's reservations about putting herself in the spotlight, the evening goes off without a hitch. At least, until she does a reading and a customer goes from chatty to dead in a flash, poisoned after sipping a toxic substance recently grown in the greenhouse. Worse, Shay's assistant is suspected of intentionally serving the lethal brew and committing cold-blooded murder. Now, aided only by Liam and her dog Spirit, Shay must exonerate her employee and save the future of Crystals & CuriosiTeas. But when clues start lining up like leaves in a teacup, she'll need to understand the signs right in front of her to catch the manipulative murderer before it's too late . . .
