Of Wards and Whispers. The Erthea Academy Chronicles, #3

The academy was built to protect the world from what lies beyond it. But some secrets were never meant to stay buried. When a tremor shakes Erthea Academy in the dead of night, Vivienne knows it's no accident. Burned wards, warped runes, and a fragment of living magic point to something ancient beneath the school's foundations. As the wards twist and the teachers close ranks, Vivienne and Diego are silenced.
Trusting the wrong person could cost them their freedom. Trusting no one might cost them the world. Whispers from the past speak of a fallen spire, a broken seal, and a buried heart that should never wake. The deeper they dig, the more Vivienne realises the academy isn't guarding knowledge - it's hiding a doorway.
