In the continuation of Tamsyn Muir's best-selling Locked Tomb Series, 'Nona the Ninth' introduces readers to a heroine who faces an extraordinary crisis. Nona, appearing as a normal individual, has been harboring a secret: she inhabits a stranger's body and fears the inevitable return to its rightful owner. Her relatively ordinary life is disrupted when her city becomes a battleground under siege, with undead hordes imminent. As if that wasn't enough, a colossal blue sphere looms overhead, threatening total annihilation. With the last bastion of the Cohort encircled by the bloodthirsty forces of the Blood of Eden, Nona finds herself thrust into a role she did not choose—to be the savior armed by the Nine Houses. Despite the apocalyptic situation, her heart yearns for simple pleasures and the company of cherished ones, yet her dreams of a woman with a skull-painted face suggest that her battle is linked to deeper mysteries.
