Seven stonecallers bled into the stone to chain a god.Only a sliver of him got loose.Renna gave her blood to the binding the night the god Aegir woke beneath the dolmen.She watched Alaric Harker drive his iron knife across his palm and seal the fissure with the last of his flesh.She felt the chant rise through the ley lines, old words no human throat was ever meant to shape.For a heartbeat, it held.Then a thought of Aegir the size of a fingernail slipped through the closing seal, coiled into a watching raven, and flew south.Aegir is not a god of rivers. He is a god of weight, of the pressure that bends mountains, of the dark below the dark where stone remembers being lava.And one piece of him is awake in the world.The rite was supposed to be perfect. Three years of research in the Grey Archives, tested on slate and limestone and black basalt, certain every single time.On a god, certainty is a luxury no one survives.Now the binding is failing. The Fingernail stones are cracking. A raven with white-then-black eyes is gathering something that should have stayed buried, and the only people who knew the working are dying with their hands fused to the granite.Renna carries fen-magic in her blood, the kind that threads through rock like roots.She is also the last one left who remembers how the circle was sealed."He's pushing," she said, voice thin. "He knows."Between her and the rising god stand a king who wants the old magic for a crown, a fae court that bargains in centuries, and a prophecy that names a price no sane person would pay.To stop Aegir, Renna will have to walk back into the stone that swallowed her teacher whole, finish a working that has already killed everyone wiser than her, and decide how much of herself she is willing to feed to the dark to keep the world from breaking.Because some debts are paid in blood.And the stone always collects.Stonecallers is a dark, mythic epic fantasy about blood magic, an awakening god, a doomed binding, sacrifice, grief, and a young woman who must finish what her elders began.Perfect for readers who love earthy low fantasy, ancient prophecies, slow-burn dread, hard-won magic, and heroines forged by loss. A standalone fantasy with a fierce, earned ending.
