As a "Gifted," Lynn Ingram can see the angels walking openly among the people of Boston, Massachusetts. As entities with no corporeal manifestation the Angelus rely on the Gifted whenever a physical link to humanity is needed. Drawn into a maelstrom of deception, agendas, and millennia of conflict, Lynn finds her life inexplicably bound to the group of Angelus in her principality. Opposed by the Fallen, she finds out first hand that the war between the two angelic factions has never ended. And in the fight for control over the sea of humanity, Lynn's own struggle for truth takes her outside the borders binding faith, dogma, and religion.
