Anathema (The Eating Woods #1) - Keri Lake

A spellbinding gothic dark fantasy about a shunned woman who is forced beyond the mortal realm’s forbidden boundary, into a terrifying world of cursed souls and grotesque creatures. Only the banished know what lies beyond the woods … There are whispers about what lurks in Witch Knell—the forest where sinners go to die. The villagers call it The Eating Woods because what’s taken is never given back. Only those who’ve lost their senses would dare to go near it.
