free audio of The Magna Carta?

Has anyone found a free audio version of The Magna Carta by James Daugherty? My daughter has had so much on her plate with The Nutcracker rehearsals and performance and I let her off the hook on a few things last week. I want to catch her up and was hoping to find a free audio of The Magna Carta from the SCM

Middle Ages Module. This way she would have a little bit less to read this month. I know I could do the free trial of audible and then cancel before 30 days. I think it is nice and has a lot of selections but $14.95 a month is a lot. Any suggestions? Didn’t see it on librivox.
