Sir,

Loved the answer to the previous "Sawyer library" question and wanted to add a follow-up. I noticed his first two books are young adult novels. Is this a theme? Or just coincidence?

And the island isn't a tesseract, is it?

Or is it?

(dum-dum-DUM!)

i think it may be some kind of polygon, but geometry was never one of my strong suits.

Great answer! Thanks. :)
