The Hungry Dark - Michael Coolwood - Bog

Every fire witch is cursed, but Melita considers herself more cursed than most.
Exiled to the edge of the world, because of her chronic illness, her only joy comes from exploring the long-dead city of Tenebro. Monsters lurk in Tenebro, devious traps seek to sever your connection to reality and then, of course, there's the Hungry Dark itself, which can strip the flesh from your bones in mere seconds. Melita isn't bothered by the monsters, she's good friends with one of the traps and she loves the Hungry Dark because it's where her light shines brightest. Tenebro is the place Melita goes to leave her symptoms behind.
When a mob attacks Melita's village for harbouring exiles, she flees to the dark with her friend and fellow cave raider Teya. Together, they'll delve deeper than ever before, chasing a myth which might hold the key to keeping their village safe from rampaging humans once and for all. The creatures of the dark want Melita's head, but her illness is the real threat, and that's something she can no-longer run from.
