Perpetual Booknerds discussion

Okay so now I'm suspicious. Are they not telling him things hoping to trick him into staying? Hiding truths is never a good thing. Oh and what about his thoughts that the place has a magic that makes you happy and content so you want to stay and stay happy even being stuck in the same day every day. Still suspicious and not sure I trust any of them. Also dudes gift and collecting hearts....creeptastic. I want to know more answers what's this huge thing that brought the other bird to them?
