The Emperor of Nihon-Ja is the tenth thrilling book in John Flanagan's Ranger's Apprentice series - over eight million sold worldwide. When Horace travels to the exotic land of Nihon-Ja, it isn't long before he finds himself pulled into a battle that is not his - but one he knows in his heart he must wage. A kingdom teeters on the edge of chaos when the Nihon-Ja emperor, a defender of the common man, is forcibly overthrown, and only Horace, Will and his companions can restore the emperor to the throne.

Victory lies in the hands of an inexperienced group of fighters, and it's anybody's guess who will make the journey home to Araluen . . .
