Thor is furious at Freya. She just called him a minion and pulled his hair. He wishes he didn't have to live with that insufferable girl. But he does, because Freya is his twin sister! Despite his anger with her he also misses how they used to have fun together before she lost her humor and turned into a pre-teen with mood swings. All Freya cares about now is Luke, the seventh grader whom she has a major crush on, and Charlotte her best friend, who is as complicated as she is. Girls are lame! Can it really be that the only thing they have in common right now is their favorite teacher, who tells amazing stories of the ancient Viking gods?
