Use the command line to get the URLs for each chapter?
Go to conqueringthecommandline.com/book
Save the page source
Insert the filename into the script below
Alternatively, omit filename and pipe the source of the page to the script
Works with BSD sed as well as GNU sed; first lesson: portability
a=$(printf '\004')
sed 's/s3_url/'"$a"'&/' \
|tr '\004' '\012' \
|exec sed '
s/\\u0026/\&/g;
s/.*s3_url.:.//g;
s/\".*//g;
/https:.*Amz/!d;
' filename
I do not recommend this "book". Look at the hoops they make readers jump through. Try grymoire.com; much better and no Javascript required
