A Fortress of Grey Ice is a fantasy novel by British writer J. V. Jones, the second book in the Sword of Shadows series.

A Fortress of Grey Ice represents a greater division of storylines than was present in the first book.

The novel opens rather dramatically with new characters and settings, then moves quickly to Ash March's abrupt and covert departure from Raif in order to join the Sull.

Left with the Listener, Raif finds himself alone, now abandoned by clan and friend, cut off from everyone and everything that he loves.

Embittered and resentful of the lore that claims him as Watcher of the Dead, Raif will wander the edge of the Want until he finds the only group willing to accept an outcast and renegade, the outlaw Maimed Men.
