Camp Zodiac (editing)
When North was detected as a Half Blood, she was kidnapped from school and was brought to Camp Zodiac, a safe place for children of the 12 Zodiacs.
But the Zodiacs are mad, and there're taking it out on other Zodiacs children at Camp Zodiac.
After a surprise attack, North comes to conclusions that she must be the one to settle the Zodiacs. She leaves behind her friends and her boyfriend, who is in a coma after the attack, and risks her life to save her camp.
