Decades before he becomes one of the most storied figures in Revelation Space, Nevil Clavain is a Coalition soldier facing the reclusive Conjoiner faction dug into Mars. When the attack he is part of goes wrong, a Conjoiner girl named Felka saves him and changes him permanently, and what he learns about the Wall's true purpose sends him across enemy lines for good. The opening chapter of Clavain's long, uneasy history.
