I'm reading through the Josie Riesman book. Shorter chapters should have been the first change the editor pushed for. I don't mean editing out most of the content. Keep everything. Just split it up into smaller, more digestible chunks. The chapters are waaaaaaaaaaaaaaaaaay too long, and they really have no reason to be.
Other than that, it's informative so far. Dark and depressing - as you would expect - but informative.
