La balada de los unicornios

The School of Gadgets and Professions accepts only the most brilliant young students. They are capable of creating motorised houses, flying hats and other such feats. Ágata McLeod is one of the school's best students, but there are a lot of things she doesn't know about the school... or its past. The inventor will have to travel back to the beginning of the world in a quest full of adventures and dangers. Fantasy and science combine in a fight to the death between ravens and unicorns.
