I think we might need to look a bit at Cory Doctorow. He is the author of both Ready Player One and Little Brother.
As far as I know, the phrase we found in the qr-code leading to Again.7z has yet to be used. Can someone please verify this?
Edit: "that phrase" being: "Never underestimate the determination of a kid who is time-rich and cash-poor."
Also, I just now realised that both these books are in the bookcase behind her in that google-video-chat-thingy screenshot.
I have posted that yesterday.
Actually all books whose titles I could make out and also links to them.
Check my previous posts, you will find them.
EDIT: Guys check my post and the link for clues pls.
