In 33 A.D., the 11-year-old Breaca (later Boudica, or "Bringer of Victory") longs to become a Dreamer, a mystical leader who can foretell the future, but, having killed her mother's killer, has proven herself a warrior. Dreaming the Eagle sweeps from the turmoil of battle to the intimacy of Boudica's loving relationship with her brother, Ban; from the fight for honor to the magic of an animistic natural world that speaks back to the Celtic tribes.
