Rea's Blood continues the alternate history enmity of the long-lived two Qayins, and of Amy Rea, adopted daughter of Samadeya-Qayin, the ally of the Almighty. It follows Amy's career from her post-Academy appointment as second officer to the Royal Army Naval Corps frigate Boudicca, her rapid promotion to commodore, then Vice-Admiral, and finally Admiral of the Orange aboard Victory.
Her novel tactics and ways of dealing with her shipmates become Royal Navy doctrine. Rea cultivates a band of fellow officers who will follow her "to hell and back" and most of them do so for her last battle against enemy nations Spain and France off Trafalgar Point, where she is shot down by snipers as she resolutely stands in full uniform on Victory's quarterdeck. But who was Amy Rae, what was her great secret, and why does she have so many look-alikes?
