Few villagers are happy when Takuda comes home to investigate a foiled abduction, and local police enlist powerful forces to shut him out. Takuda sacrifices his career and family honor to solve the string of disappearances in the dark and backward valley of his youth, but more than a job is at stake. Behind the conspiracy lurks the Kappa, a monstrous living relic of Japan's pagan prehistory. Protected long ago by a horrible pact with local farmers and now by coldly calculated corporate interests, the Kappa drains the valley's lifeblood, one villager at a time.
Takuda and his wife, Yumi, are among the few who have escaped the valley, but no one gets away unscarred. When Takuda digs into the valley's mysteries, Yumi's heart breaks all over again. She wants justice for her murdered son, but she needs an end to grief. Even if Takuda survives the Kappa, the ordeal may end his marriage.
With Yumi's tortured blessing, Takuda dedicates his life to ending the Drowning God's centuries-long reign of terror. He can't do it alone. A laconic junior officer and a disarmingly cheerful Buddhist priest convince Takuda to let them join in the final battle, where failure means death--or worse. The journey of these three unlikely warriors from uneasy alliance to efficient team turns THE DROWNING GOD's mystery into an adventure in friendship, sacrifice and courage.
