As the sun rises over the Approaches, Tacenda’s world goes dark. Blessed by an ancient entity known as the Bog, she and her twin sister are born with the power to protect their village from danger—Willia with a sword; Tacenda with a song. Their blessing is entwined with a curse though: one sister is blind by day, the other by night. Tacenda dreads the darkness—longing to see the sun once in her life—yet she dutifully accepts her fate, until the day her warding song fails to defend against a swarm of geists. Leading the attack is a masked figure believed to be the Man of the Manor—a local lord possessing strange magic, who keeps even stranger company. Unable to protect her people, Tacenda embarks on a mission to avenge them. A night that begins with an assassination attempt spirals into a race to unravel a mystery, as Tacenda is brought face to face with the true nature of her power.
