The new ninja

"Nya has always been a key part of the ninja's success, whether she's organizing operations from the Destiny's Bounty or fighting bad guys in her Samurai X mech. Cole, Jay, Kai, Lloyd, and Zane depend on Nya's fierce intelligence and awesome battle skills. Now that Nya's a full-fledged ninja--the Master of Water--she's got more to offer the team than ever before. So when a call for help comes in, she decides to give the guys a night off. After all, what could go wrong? As it turns out, a whole lot! The new ninja might be a little too independent. Can Nya figure out how to work together and take one for the team?"--Back cover.
