Where Light Fears to Fall. Hollow Veil Chronicles, #1

The world does not fear witches because they are wicked. It fears them because they are powerful. In the ruins of a city that burns its heretics, a coven hides in shadow - bound by blood, fractured by prophecy. Their magic can heal or destroy, but the cost is always steep: a scar for every wound mended, a life for every fire quenched. When the Holy Order sharpens its blades and the skies bleed with omen, the witches must decide: protect the fragile circle they've built, or risk annihilation to reclaim a world that was never meant to love them.
But even light has shadows, and some darkness cannot be banished. Because there are places where light itself dares not fall. A gothic fantasy of forbidden love, ancient magic, and survival at the edge of ruin.
