Strange alliances are forged among the fae as Macsen Cadoc and his fae allies attempt to defeat the Milesians, Irish huntresses who bear a grudge against the sidhe.
Failure will bring Macsen to his knees; success may do the same, unless he and Bran Fionnan, once a captive of the huntresses, can succeed in sowing seeds of peace. Yet even while some attempt to find a middle ground and forge a place where tolerance can flower, a new power rises, a threat to them all.
The Church of Rome aims to win the earth from its immortal rivals, even if doing so comes at the price of magic itself. It will be up to Macsen to make a choice that might save the fae and all that sustains them...but only Bran has the power to convince him to do what is right.
Can mortal and immortal overcome the conflicts that divide them when some must hunt others to survive? Is love stronger than anything—even a Fae King's pride?
