The Kaisho

From New York Times bestselling author Eric Lustbader, the suspense mastermind behind the smash bestsellers featuring Robert Ludlum’s™ Jason Bourne, comes a blockbuster thriller of one man’s debt of honor—and his ultimate destiny.

Years ago, Nicholas Linnear, a.k.a. “the Ninja,” made a promise to his father: If a man named Mikio Okami ever sought his help, he would respond without question, no matter the cost.

Now the time has come to fulfill his pledge. Okami is the Kaisho—the boss of bosses of the Yakuza, the Japanese underworld—and in his Venice headquarters, he realizes that he has been marked for death.

But the identity of the assassin and the inexorable compulsion that drives him are shrouded in mysticism and madness.

Honor bound to protect Okami, Linnear is prepared to make the ultimate sacrifice: a descent into a chasm of knowledge so potent, of dangers so unfathomable, that even if he survives, he will emerge changed forever.
