Resources regarding the 1934 Minneapolis general strike

I have an elderly relative who is interested in the 1934 Minneapolis strike (he is related to one of the people involved who was later pictured in Mexico with Trotsky). I'd like to find a book for him regarding this topic and I was curious if anyone here had some insight. I know Farrell Dobs wrote extensively on this but judging from the reviews only I'm not sure if it's focused on the events or more of a guidebook for labor organizers. I'd really prefer the former to the latter. Any help would be appreciated.
