When Duff O’Brien moves to Hiawassee, Georgia after a traumatic experience in her Michigan hometown, she’s looking to finish high school with her head down and work at her beloved granny’s barbeque joint. Enter classmate Marian “Mac” Shepherd: ambitious, rough around the edges, and devoted to Duff immediately. The two best friends pick up instruments and along with their new pal, recently-disgraced golden girl Quincy Banks, form The Scottish Play, the hardest-rocking all-female band North Georgia has ever seen.
Five years later, The Scottish Play is living and playing together in Athens, Georgia, getting all the gigs they can with the help of their rhythm guitarist Rosalyn “Ross” Smith and their manager, legendary record executive and father figure Ian Duncan. When the women meet the handsome and enigmatic Lawrence MacLaren at local hot spot The Grit, it’s love at first sight for Marian—and Lawrence envisions even bigger and better things for his new girlfriend’s band. But when Ian mysteriously drops dead, and teetotaler Quincy succumbs to a drug overdose soon after, Duff and Ross begin to suspect that Mac and Lawrence may be involved. Does this have anything to do with the prophecies from The Hecks, a wickedly handsome male trio of Hiawassee witches—one of whom Duff is now dating? And as the band journeys to Scotland’s historic Glamis Castle for the show of a lifetime, Duff wonders if she ever really knew her best friend Mac at all—and more urgently, is she next?
