The Mighty Zodiac Series by J. Torres, Corin Howell, Maarta Laiho

When the Blue Dragon dies, six stars fall out of the night sky! Ailing Master Long, leader of the Mighty Zodiac, orders his warriors to gather the stars, lest they fall into the hands of the malevolent Moon Rabbit Army. With the stars, the Mighty Zodiac may yet revive their master, rescue their world, and restore the light. Without the stars, the darkness threatens to divide the tribes and destroy Gaya...

One dark and quiet night in Gaya, six stars fall from the sky. Master Long, the ailing leader of the Mighty Zodiac, sends his warriors out to collect the stars before the Moon Rabbit Army can get their paws on them first. If the Rabbits get the stars, the balance of nature and the fate of all of Gaya will be in danger. But Long's plans to use the stars to "cure" his illness may be just as dangerous and bring an end to the Mighty Zodiac itself."
