Katana Nidan: The Unwritten Koan

By: Warner, Ken

A young adult urban fantasy of magical martial arts, secret scrolls and a teenage student racing to master new skills before her school comes under attack. Book two in a coming-of-age series of chi magic, mentors and ancient rivalries.

A Stolen Scroll. A Secret Worth Killing For. One Student Standing In The Way.

The Arashi have stolen the Scroll of the Five Masters from the Hall of the Dragon, but their master can't unlock its secret: the key to immortality. Convinced the answer lies in the temples' secret archives, he prepares to strike at the Hall itself.

The masters launch a covert mission to stop him, yet every day of silence brings the attack closer. Katana has already mastered two of the mysterious Chen Do skills and is close to a third. When the enemy finally infiltrates the Hall, her mentor's fate will rest in her hands.

Perfect for fans of Patricia Briggs, Ilona Andrews and Kelley Armstrong.
