It's going on a lot in Matti's and Otto's lives. Matti has a VERY strange feeling when he's looking at Mina, who is the new girl in their class and very good in playing soccer. Recently Otto has begun to comb his hair. And as if that was not strange enough, Matti's dad suddenly appears in front of their door, the dad who didn't get in touch with him for more than five years. But Otto's mum moves out. For now.To make friends with Mina is a little bit difficult, because she doesn't even want to tell where she lives. However Matti and Otto want to give her extra lessons in Math, so that she won't be bothered by the horrible Misses "Streiter" anymore. A great mess for the two boys. But they absolutely need to find out what's wrong with Mina...A modern city children story about boys in love, parents without any plans and tough girls. About "Hotte Zimmermann", "Bruda Berlin" and the "Horrific Twins". A story about big secrets and great emotions.
