The Starsplinters are aeldari corsairs, raiders and reavers of the void, and Baron Myrin Stormdawn is one of their greatest leaders. When his running conflict with the Badskab Bukkaneers of Uzgul da Magnificent escalates in unexpected ways, Myrin is forced into an alliance with Taenar Leotharan, an exiled admiral from his former home: the craftworld Ilmaren. As Taenar is forced to adapt to the unfettered life of the corsair, whose freedom is a double-edged sword, Myrin faces challenges of his own. For when a Starsplinters' authority rests on the success of their last voyage and the whims of their feared commander, Princess Tishria, Uzgul da Magnificent's freebooters may not be the deadliest threat.
