The Grave Raven - Kevan Dale - Bog

A rising tide of the infernal threatens to engulf Boston. Only a harrowing race into a realm of displaced magic can stop it.
Kate Finch keeps her promises. Even when they pull her deeper into the colony’s power struggles and political intrigues. Even when they entangle her further with the shadowy magic rising in the woods and vales around Salem. But as August Swaine’s experiments grow more brash, Finch’s loyalty faces to the ultimate test. When keeping her most ill-advised promise uncovers the true extent of her master’s folly, she faces a reckoning beyond any witchcraft, spells, or wards.
Finch promised herself she’d never lose another loved one to a demon.
Is it the one promise she has to break?
