In response to a request for an update by a fan, Tor replied:
"J. V. Jones is currently hard at work on the 5th Sword of Shadows novel, which we're hoping to bring you sometime next year!"The previous volume in the series, Watcher of the Dead, was published in 2010. Jones her not updated her website or her Twitter since 2011, leaving readers pondering the fate of the series. However, lengthy gaps between volumes are not unusual: the third volume, A Sword from Red Ice, was published in 2007 five years after the second, A Cavern of Black Ice.
