A night spent sleeping on dirt and leaves is not how Claire Matchett expected to spend her vacation. She thought this would be a break. A week of hiking and hot tubs with two other couple friends. Then Claire’s minivan breaks down on a lonely dirt road. With no cell reception, the group has no choice but to hike the rest of the way to their hotel. But it turns out the woods aren’t as easy to navigate as they thought. Hours later, they are lost. Hopelessly lost. And as they navigate deeper into the woods, the members of their party are struck down mysteriously one by one.

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.

Tess Strebel can’t recognize her own face. She can’t recognize her home. Her bedroom is unfamiliar. And she can’t remember the handsome stranger lying next to her in bed. A stranger who claims he’s her husband. Tess reads a letter in her own handwriting, composed during a rare lucid day, explaining her life as it now exists: she was in a terrible car accident one year ago. Every morning, she wakes up unable to remember most of the last decade. Including her own wedding.
