Bakugan - Book - The Bakugan Brawlers

One day, strange cards began to fall from the sky. All over the world, kids picked them up and created a battle game. The best players were Dan, Marucho, Runo, Shun, Julie and Alice. They called the monsters on the cards "Bakugans" and their team the "Bakugan Battle Brawlers".

But these aren't just cards. And it's more than a game. The cards correspond to a world called Vestroia where a fierce battle is raging-a battle that could destroy both Vestroia and the human world. Now it is up to Dan and his friends to save both places. What they thought was just a game has become a race to restore peace throughout the universe!
