There is some serious talent here and some awe inspiring writing, some of it very dark, very noir and very hard hitting. This writing is as good as SF written by men only with an added insight into the female mind and the emotional relations between men and women.
There are some experimental stories here, too, lacking either plot or coherence. And there is one that's nothing more than a woman whining about keeping house and raising children (oh, the horror!). Okay, well, it was the sixties...
The pick of the litter:
That only a Mother by Judith Merril is superbly understated and merciless in both its realism and its circumstance.
Contagion by Catharine MacLean is a bloody good space opera yarn with the added dimension of male female relations.
The Anything Box by Zenna Henderson will move you as all her stories will.
When I Was Miss Day by Sonya Hess is a stream of consciousness look inside the mind of an alien shape shifter pimped to the humans by her drug addicted relatives. Done effectively, honestly and touchingly without the need of graphic details or obscenity.
The Funeral by Kate Wilhelm is great writing as always about the perpetual benighted state of humanity, with all its corruption and ignorance and cruelty.
The Ship Who Sang by Anne McCaffrey is hard sf with some very moving elements of a hopeless first love lost which is very moving.
Death Between Stars by M. Z. Bradley begins well, but ends so abruptly that one wonders if a deadline was upon her. See what you think.
No Woman Born by C.L.Moore is the only example of SF from the 1940's here, and is typical of the best of the period. It explores what makes a woman human and what gives her sex appeal and does it well.
Tiptree's "The Women Men Don't See" is a story so good that it warrants buying either this book or this collection: Her Smoke Rose Up Forever. Her writing is amazingly good. She is able as any man of assuming a male's viewpoint and her plots and prose just won't let you go. And, man, does she know the world and the inside of men's skulls!
Special mention: Of Mist and Grass and Sand by Vonda McIntyre is an award winning story and interesting but oh so poorly executed, predictable and cloyingly phrased this reader could barely wade through the overdone, archaic dialog and silly melodrama.
The other stories may appeal to those who enjoy more modern writing of whatever genre. There is a second collection in this series spanning the seventies to the nineties. After reading this one I won't be buying it.
