I read this one and Ready Player One
back to back--how's that for geek reading heaven?
This needs to be a movie. You have the Everyman protagonist, the brilliant love interest, the best bud from middle school, the mysterious bookshop owner, messages from the past, a vast conspiracy that might or might not be eeeeevil, and a race to find the way to immortality. What else do you need?
I'm telling you, it would be a hit. Somebody get on this!
