Ah right, well the book in question was Red Hat Certified Technician & Engineer (RHCT and RHCE) Training Guide and Administrator's Reference by Asghar Ghori (ISBN-10: 1615844309 and ISBN-13: 978-1615844302). I've got it uploaded
here but I'll willing to up it anywhere. If they need access to the Kindle format, I suppose we can try to work around that.
I'll try searching for details and contacting the various developers with the information.
