Super Cool Finished Book

Previously, Anna Bea, Nils and their friends from the lowest caste in the school were disturbed by the super cool. But in the second book by A. Audgild Sulberg, it seems that the spinsters have already done so much to each other and to everyone around them that they have ceased to be reckoned with. Now friends can catch their breath and celebrate their unexpected freedom together. But is it really that easy to be super cool and popular? Do you have to be high caste to play in the best school band? And will the lower and upper castes be able to find a common language? Everything will be decided during the most fantastic Halloween party, to which you are also invited.
