Charlie’s Magic. The Bitey Book

I, Charlie Vernier, and my friend Mangustina ended up in a school where magic is prohibited. Meanwhile, the magical world is in danger outside its walls! Our talented teacher Lin is imprisoned. My powerful grandmother has disappeared into a magical portal, and Mangustina's "Bitey Book" – the main artifact of every wizard – has been stolen. But it seems we know who is to blame. Judge Dandelion wants to take control of all the magic in the city. I must stop him and help my friends. But how can I outsmart evil without a single spell at hand?
