Humanities: The Foundations?

Okay I'm kinda in a messed up situation. I registered for this online Humanities cl days after the deadline to use book vouchers. I really don't have the money to pay for it out of pocket so does anyone know where I can read the book online??? The course is called Humanities: The Foundations. The author's name is Sirius and the publisher is McGraw-Hill. Can someone please help me out!!!!!
