Joy, 57, from Wroughton, was inspired to write the story by her 11-year-old granddaughter Natasha who loves to hear spooky tales.
The story follows the adventures of a young girl, Mia, who investigates strange events by her grandmother’s home alongside her friend Safi.
The book’s been published in paperback and Kindle on Amazon and copies will be available to buy and be signed by the author.
The launch event will be held at the Skittle Alley in the White Hart pub in Wroughton on May 20.
