The Demon in the Wood (The Shadow and Bone Trilogy, #0.5)

by Leigh Bardugo

That was how they always found Grisha. He and his mother followed legends, whispers, tales of sorcerers and witches, of demons in the forests. Stories like that had led them to a tribe of Squallers camped along the western shore, to Baba Anezka and her cave of mirrors, to Petyr of Brevno and Magda of the black woods.
