[The books are a mix of a few things. There's academic textbooks and manuals on teaching and a bunch of stuff to do with a place called 'University of Manchester'. There's spell books and recipes for potions and tomes about 'Communing With Beings Most Exotic And Infernal'.]

[One that seems the most well-read of all is a book about the Void. It's mostly theories and conjecture, because the Void is so poorly understood by mankind. A lot of Nessa's own notes are scribbled in the margins in some fairly difficult to decipher handwriting.]
