Absolutely brilliant, incredible, underrated book. Heard of it by accident, surprise ; I'm so glad I checked it up. This is THE book you need to read to understand how exactly is that world fucked up. Although it's showing the reality of the prison's world, to be true, it's showing our disgrace of a disgusting species in all its splendor.
A bit hard to read, because it's a very specific writing style. A terrific one, that is worth every effort.
A woke book. The best book I've read in a long, long time.
