Yep, Adi could tell them all something about the book. He'd try to make it as brief as possible. He didn't like being in the spotlight for too long.

"It's about a man named Griffin who arrives at a village totally covered up. He's wearing gloves, hat and long sleeved clothing and his face is covered in bandages. Griffin did an experiment on a cat then on himself making both him and the cat invisible. That's why he went to the village- to work on a cure for the invisibility.'' Pause. So why would Adi recommend the book?

"I would recommend the book because it is very entertaining, action packed but most of all, it gets your curiosity going. I think from a wizard's point of view, it would be a rather interesting question about if muggles could actually make themselves invisible in the future.'' Of course anything's possible.
