Crossing the Finish Line: Completing College at America's Public Universities

This is a new book by William Bowen, Matthew Chingos, and Michael McPherson. It's getting a lot of press coverage, but I haven't read it and so I can't vouch for its usefulness. I'm a bit skeptical about it, because it only focuses on public colleges, and only 21 of them at that. But I'm open-minded and would love to hear if this book adds anything new to the debate about college value and college graduation rates.
