Hey TRP :) Long time lurker here. I recently stumbled upon The Book of Pook website and PDF, alongside with a crappy EPUB file. I decided to make it much better and here is the result (uploaded to different websites, sorry if they are bad, they were just first results in Google):

EPUB http://s000.tinyupload.com/?file_id=20125177737682341249 http://www.filedropper.com/bookofpookthe-pook http://www.megafileupload.com/fwMI/Book_of_Pook,_The_-_Pook.epub

MOBI http://s000.tinyupload.com/?file_id=03796621276473195673 http://www.filedropper.com/bookofpookthe-pook_1 http://www.megafileupload.com/fwMJ/Book_of_Pook,_The_-_Pook.mobi

WEBPAGE https://bookofpook.neocities.org/

PDF from the WEBPAGE https://bookofpook.neocities.org/TheBookofPook.pdf

I used EpubPress Chrome extension for extracting stuff from the webpage and Calibre for creating table of contents and polishing.
