Following a devastating earthquake and tsunami, a young man in Japan finds a stray dog outside a convenience store. The dog's tag says "Tamon," a name evocative of the guardian deity of the north. The man decides to keep Tamon, becoming the first in a series of owners on the dog's five-year journey to find his beloved first owner, Hikaru, a boy who has not spoken since the tsunami. An agent of fate, Tamon is a gift to everyone who welcomes him into their life.

At once heart-rending and heart-warming, intimate and panoramic, suspenseful and luminous--and deepened in its emotion by the author's mastery of the gritty details and hardscrabble circumstances that define the lives of the various people who take Tamon in on his journey--this bestselling, award-winning novel weaves a feel-good tale of survival, resilience, and love beyond measure.
