England, 1989. Over the course of a burning hot summer, two very different men - traumatized Falklands veteran Calvert, and affable, chaotic Redbone - set out nightly in a clapped-out camper van to undertake an extraordinary project. Under cover of darkness, the two men traverse the fields of rural England in secret, forming crop circles in elaborate and mysterious patterns. From the bestselling author of "The Offing".
