Samurai Jack is Cartoon Network's newest hit from the creator of Dexter's Lab. "Mayhem Mountain" is an all-new, original story in which the heroic warrior furthers his quest to defeat Aku.

In his first original chapter book adventure, Jack must travel over a perilous mountain range to find a wise man who can help him return to his own time. Along the way, he'll battle the mysterious Shen -- mischievous spirits that can work for good or evil -- and come face-to-face with his shape-shifting nemesis, Aku.
