like others on here said, read the book and get it as a workbook rather than reading it for solid information or history.

I think there are some useful practices for groups, but the book seemed weirdly anti education but I don't think it was trying to be? also weird tribal exceptionalism in the first part (namely a quote that amounted to something to the tune of "indigenous people have done mutual aid successfully before white people came in!"). reminder that, as an indigenous person, we are never and never were a monolith. 

that kinda brings me to my next point that this book really skimps on examples/evidence of why their ideas work. if youre already deep into leftist theory and history then I think it's useful for the exercises, but not helpful to those who are starting for the first time in the space. really it's just the middle part that I find having useful information. ymmv based on your background and if you get the book rather than listening, and if you already are looking into building a mutual aid group
