Bridge of courage - Masashi Kishimoto

Naruto is a ninja-in-training with a need for attention, a knack for mischief, and sealed within him, a strange, formidable power. His antics amuse his instructor Kakashi and irritate his teammates, intense Sasuki and witty Sakura, but Naruto is serious about becoming the greatest ninja in the village of Konohagakure!

Zabuza, the ninja assassin, was stopped from his first try at killing Tazuna the bridgebuilder - but Zabuza still lives! While the ninjas recover from their injuries, Kakashi puts Naruto, Sasuke and Sakura on a strict training regimen to protect Tazuna's family - including Tazuna's embittered grandson Inari - and prepare for Zabuza's next attack. But the next time won't be as easy, because joining Zabuza is his apprentice, Haku. And as the bridge comes closer to completion, our heroes must be willing to die - or kill - to protect the ones they love.
