Everyone hates summer homework, don't they? Unfortunately for Bella, what would have been the time when she could finally do whatever she wanted was plagued with just that. But this summer homework isn't like the "write an essay" type of homework, or the "make a website" type. No, this is the "save the world" type of homework (which is not really homework at all!), specifically to defeat Bella's former science teacher, Ms. Ana. All of this while trying to lead a whole team of students, boys and girls. Losses, gains, happiness, grief... And at the same time, the fight to defeat the "Bad Bad Teachers" have made this the hardest assignment given to the students thus far. Clashes from people left and right with seemingly no chance to keep cool, will Bella and the others ever get even a passing grade on their homework?
