In the shadowed attic of a Welsh farm, a secret slumbers that could shatter an empire. For two centuries, whispered from grandmother to grandchild, a forbidden truth endures: Ann, born in 1829 amid England's fog-shrouded intrigue, holds a dangerous tie to the British crown. As the empire teeters on the brink of revolution, noble visionaries like John Lambton, Earl of Durham - a radical Whig and Freemason - plot to forge a progressive monarchy, sparing England the bloody revolutions of France and America.

Smuggled to the remote hills of Wales, Ann's life is one of toil, bound by a secretive Freemason lodge. Yet fleeting dreams of a sister keep her fire alive. Ascending to the throne in 1837, Queen Victoria navigates scandals and reformist dreams, haunted by a hidden sibling. Stolen reunions, from a childhood laugh by the sea to a tearful embrace, bind them in a love that could topple Victoria's throne. In 2019, a descendant unearths cryptic letters, unraveling a conspiracy that echoes through time.

Granny in the Attic weaves heart-pounding intrigue with a saga of sisterhood, daring listeners to question the House of Windsor's hidden fractures. For fans of The Crown and The Other Boleyn Girl, this debut unveils a revolution too bold to stay buried.
