Yuki Hirano is just out of high school when his parents enroll him, against his will, in a forestry training program in the remote mountain village of Kamusari. No phone, no internet, no shopping. Just a small, inviting community where the most common expression is “take it easy.” At first, Yuki is exhausted, fumbles with the tools, asks silly questions, and feels like an outcast. Kamusari is the last place a city boy from Yokohama wants to spend a year of his life. But as resistant as he might be, the scent of the cedars and the staggering beauty of the region have a pull.

Inspired as a boy by the multiple meanings to be found for a single word in the dictionary, Kohei Araki is devoted to the notion that a dictionary is a boat to carry us across the sea of words. But after thirty-seven years creating them at Gembu Books, it's time for him to retire and find his replacement. He discovers a kindred spirit in Mitsuya Majime - a young, disheveled square peg with a penchant for collecting antiquarian books and a background in linguistics - whom he swipes from his company's sales department.

The Thief is a seasoned pickpocket. Anonymous in his tailored suit, he weaves in and out of Tokyo crowds, stealing wallets from strangers so smoothly that sometimes he doesn't even remember the snatch. Most people are just a blur to him; nameless faces from whom he chooses his victims. He has no family, no friends, no connections.... But he does have a past, which finally catches up with him when Ishikawa, his first partner, reappears in his life and offers him a job he can't refuse.
