I checked this Book Your eBook | Awesome Resources To Grab Any eBook For Free, and found it in readanybook and zoboko, but the download button in those links seem not to work for me.
I wonder if there’s a tool to somehow fetch/get the content of each page, compress, and finally create a pdf/epub file. I can take screenshot of the google book one page by one XD, but it takes a lot of time and is inefficient.
