In this fifth entry in the "Graves Crew" series, the band of misfit laborers is united again, this time on a secret mission in search of a powerful source of magic. The White Order has come under direct attack by agents of the rebel Baron, and the key to their defeat may be Keev, whose strange magical talents have attracted attention from both sides. Accompanied by a white mage, the crew must delve into the depths of the mysterious Graemewyld to find a weapon that could end the war for good. But the forest does not tolerate intrusions, and the Baron's minions are already on their way to ensure that the quest fails.
