Scourge. Darkhurst, #1

Three undertaker brothers fight the monsters who killed their family-and uncover a plot larger and far more dangerous than they ever imagined. In a city beset by monsters, three brothers must find out who is controlling the abominations. The city-state of Ravenwood is wealthy, powerful, and corrupt. Merchant princes and guild masters wager fortunes to outmaneuver League rivals for the king's favor and advantageous trading terms.
Lord Mayor Ellor Machison wields assassins, blood witches, and forbidden magic to ensure that his powerful patrons get what they want, no matter the cost. Corran, Rigan, and Kell Valmonde are guild undertakers left to run their family's business when guards murdered their father and monsters killed their mother. Their grave magic enables them to help souls pass to the After and banish vengeful spirits.
Rigan's magic is unusually strong and enables him to hear the confessions of the dead, the secrets that would otherwise be taken to the grave. When the toll exacted by monsters and brutal guards hits close to home, and ghosts expose the hidden sins of powerful men, Corran, Rigan, and Kell become targets in a deadly game and face a choice: obey the guild or fight back and risk everything. Scourge is a fast-paced, action-packed, monster-filled fantasy adventure with non-stop twists and turns, loyal brothers, found family, forbidden magic, vengeful ghosts, high-stakes intrigue, and dangerous secrets set in a vibrantly visualized world.
