The monsters aren't just in the shadows anymore-they've made the Obelisk their hunting ground. As blood spills and the Halls descend into chaos, Iona and her allies fight to stay alive in a school that feels more like a warzone. At first, survival is all that matters. But when the death toll climbs and the magical barriers crumble, they realize the threat isn't just to them-it's to everything the Hundred Halls stands for. Battling through nightmares and closing rogue portals, the group becomes an unlikely force of protection for younger students. But something ancient and hungry is slipping through the cracks. Professor Gideon is acting strange. Blake is hiding more than ever. And when a trusted ally is sacrificed in a ritual soaked in blood, suspicion turns inward-especially toward Iona, whose growing power carries a shadow of its own. The truth is darker than any of them imagined. A forgotten god is waking. A cult is rising. And the one person they thought they could rely on may have orchestrated it all. To survive, they must flee into a realm worse than nightmares-because the final ritual has already begun.
