im having problems with the library part, I have tons of books flying around, and I keep following the way up the walls , buy ladder or creeping but once i get to the top i have no way to turn camera around and its to far to jump to the last part which i would think is where the book for the quest is, so i dont know if i have to hit something or not, am i suppose to kill flying books if so how?
please help by emailing or posting the answer

Ok i have finally beaten the library thing but now im stuck at end of the game trying to beat voldemort.
how do i do this?
