Derf's dramatic and detailed accounting of the five days of protests at Kent State University that culminated in the killing of fours students (and the severely wounding of nine others) on May 4, 1970 is thorougly researched, heavily documented and deeply affecting.  Originally scheduled to be released to coincide with the fiftieth anniversary of the killings, it was delayed due to the pandemic and has now been released to coincide with students "return" to school.  Much has transpired in the intervening four months, making this 280 page hardcover volume even more relevant.  

Here's an interview with Derf  about Kent State, from back in February (when it was assumed the book would be released in May).
