I just finished Aaron Clarey's newest book, "A World Without Men".

Gotta hand it to him, he does decent work. Short, fact-packed, no hard prescriptions, just a set of logically deduced options for what comes next for both sexes. And good prose.

Statisitical work like his becomes outdated as new data accumulates, but it's relevant for now and the data trends are probably good to rely on for a few years. Worth the read.
