Scourge Darkhurst series, book 1

Summary: Epic new fantasy from the bestselling author of The Summoner. 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 assure 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.
