The Arashi have stolen the Scroll of the Five Masters from the Hall of the Dragon, but their master cannot unlock its secret: the key to immortality. Believing the answer must lie in the temples’ secret archives, he’s on the offensive. And it’s only a matter of time before he attacks the Hall of the Dragon.



The Hall is launching a covert mission to foil his plans, but they’re running out of time. Katana has already mastered two of the mysterious Chen Do skills, and is on her way to achieving a third. But will she be powerful enough to confront the enemy when he infiltrates the Hall? In the end the fate of her mentor will lie in her hands.

Ken Warner grew up reading science fiction and fantasy; his early favorites were The Chronicles of Narnia, Dune, and of course, Lord of the Rings. When he began his martial arts training in high school, he heard many myths and legends about masters who possessed mysterious powers, typically attributed to their internal chi energy. He often thought these legends would make a great story. This ultimately led to his first books, The Katana Series. Ken continues to focus on science fiction and fantasy in his writing. He went full time with his author career late in 2020. Ken lives in Connecticut with his wife, Parveen, and their many dogs and cats.
