SPFBO9

New York City, 1859: On Samhain night, a mage pledged to the Wild Hunt is violently murdered. Tensions between the Hunt and Triona, Fey Queen of Central Park, heat up and threaten to boil over into a full-scale conflict. Sofia De Benedetti, mage and musician in Triona’s court, has her hands full making enough money to support herself and help women who are down on their luck in the rough corners of the city. Now a fey war looms and a mage killer is on the prowl. Everything Sofia has built since immigrating, and her life itself, is at risk. With the help of a cait sidhe and a tempestuous storm fey, Sofia must find the murderer before the streets of the city erupt into a magical battleground.
