Bran, Sato and Nagomi are back in this unusual story that blends historical fiction, set in imperial Japan, with fantasy, dragons and a touch of magic. The Warrior's Soul picks up where The Shadow of Black Wings leaves off. Bran is in mortal danger and disguised as a Samurai, he flees with Sato and Nagomi in search of his lost dragon. Evil however is close behind and at ever turn. James Calbraith does a wonderful job at weaving fact and fantasy into an alternative but very realistic history that pulls the reader into a rich tapestry of landscape, intrigue and history. While the story focuses on Bran and his friends, there are a few sub-plots with numerous characters, and that can get a bit confusing (especially since the names are almost all Japanese sounding). That said, I would still recommend this series.
