• "Picking up the story soon after events in <i>The Invaders </i>(2012), this engaging sequel opens aboard the <i>Heron </i>as Hal, his fellow Skandians, and their friend Lydia sail up a river in search of Zavac, the ruthless pirate who has stolen a precious relic from their village. Welcome humor lessens the dramatic tension at times, and the shipmates’ individuality and comradeship make their adventures more meaningful. [This] novel provides a satisfying conclusion to the three-book cycle that opened with <i>The Outcasts </i>(2011). [A] vigorous offshoot of the Ranger’s Apprentice series."
