The Miko (The Nicholas Linnear Series Book 2)

The New York Times–bestselling novel in which Nicholas Linnear becomes the target of an international conspiracy
When his best friend dies under suspicious circumstances, martial arts expert Nicholas Linnear vows revenge. But although he may look American, a childhood spent in the dojos of Japan taught Linnear that vengeance must never be hurried. He takes a job for the billionaire industrialist who ordered the murder, planning to befriend his target during a trip to Tokyo. But even for a modern-day ninja, there is such thing as too close for comfort.
In Tokyo, Linnear finds far more to worry about than the intricacies of Japanese business. He is being pursued by a miko: a female assassin, part ninja and part sorceress, whose beauty is matched only by her skill in combat. Drawn into a tangle of corporate intrigue, international espionage, and hedonistic sex, Linnear will have to put revenge on hold if he is to leave Japan alive.
