But when ninjas attack and betrayal strikes from a most unexpected source, can Wolverine reclaim his honor, and rescue Mariko and himself from the trap Shingen has drawn around them both? Then: The X-Men travel to Japan to rejoin their wayward teammate, but the villainous duo of Viper and the Silver Samurai want to guarantee that the mutants' story won't have a happy ending. It's secrets, shockers and broken hearts in Wolverine's legendary first solo adventure!
