First of all the main character is not a protagonist, but before reading I thought he is. Griffin is egoistic person . From Griffin’s words he not happy that invisibility happend with him, but he used his position to manipulating people and stoling.
This story finished tragically, but that was predictable because Griffin - is a young man with huge ambitions, whose find the way makes himself invisible. Ofcourse he don’t stop on this, and in long perspective he want influencing to the world. But world don’t want changing and sending helpers who’s betrayer him.
If something was mistaken in text above, thats becouse it my first book in english.
