The Blood Tide

A hostage raised among his captors, Cormac Ó Riain belongs to neither the Norse who mock him nor the Irish who disowned him. When Dublin burns and the High King Brian Boru offers him a devil's bargain—spy on the only home he's ever known or watch his father die—Cormac must walk a blade's edge between two peoples hurtling toward the bloodiest battle in Irish history. With his wife, his infant son, and the fate of kingdoms hanging in the balance, one man's loyalty will be tested to its breaking point at the tide line of Clontarf.
