I fear that is for just Schlenz's one page review, that I fully typed in above.

That's really expensive for a one page review, even though its very well written. Something needs to happen to adjust their pricing structure.

Also how much does it delve into liberation theology? That's something I found interesting at first, but the more I studied the more frustrated I became with its concepts.

Probably not as deeply as you'd want if that is your primary focus. It's a short book, and much of it is about the goats and the landscape. Corbett approaches as a Quaker, and my recollection is that he reports on liberation theology primarily as an outsider working alongside Catholics. This collection of essays memorializing him might give you a better sense of who he was: https://ccc758.files.wordpress.com/2017/06/valleyview_newsle....
