Much of this world's history has been shaped by the constant attempts to shift the balance between the individual as an autonomous, self-directing, self-centered, and unique unit and the group society, where everyone's efforts go towards the general welfare, where the individual is merely a replaceable cog. This book takes this battle to the extreme, to where, via cloning, there really are no individuals, only copies, where anyone who disturbs the group is subject to extreme measures, from execution to severe behavioral/mind control to expulsion to the wilderness. True individuals come to be considered 'defective', as they cannot always accept the wishes of the group, they keep coming up with disturbingly new and different ideas, and they place themselves ahead of the group.
From this starting point, the book is told in three distinct parts. The first section covers the period when the cloning facilities are being set up against a background of a world society in the throes of collapse. Part two is a look after several clone generations have occurred and an expedition is made to one of ruined cities to salvage needed high-tech supplies for the continuing cloning operation. The expedition exposes both the strength and the weakness of the clone groups, as they find it almost impossible to remain sane when separated from their clone 'brothers' and 'sisters'. One expedition member, Molly, grows so far away from her sisters under the stress that she really becomes an individual. Part three covers the final battle between clones and individuals, as Molly's son Mark grows up as the only 'single' in the group.
Thematically, this book is tautly conceived and executed. The later generations of the clones exemplify the problems of extreme homogeneity, as they find themselves, though extremely intelligent and quick learners, incapable of creative thought and independent action. The down sides of the individual are also exposed, showing the limitations on what one person can do when separated from the group. All of this is displayed pretty much by the character's actions, though there is some exposition via council meetings that are more philosophical statements than planning sessions.
Character development is reasonable, given that most of the clones must remain essentially 'faceless' and the time span covered means that no character lasts more than a third of the book. But this also means that no character is explored in extreme depth, which makes it hard for the reader to become emotionally attached to anyone.
Scientifically, there are problems with this book. An ecology is an extremely complex intertwined entity. When all the land animals die off (including, by specific mention, bees), there will be large affects on the plant population. Many plants can't reproduce at all without the help of certain animal species. The grasses, without a large group of herbivores to keep them in check, would very likely choke out many other plant species. Pollination becomes extremely problematic without bees. Wilhelm attempts to get around this by stating that function is taken over by ants, which would be at best much less efficient than that which occurs with bees. But Wilhelm shows none of these foreseeable affects - the forests and grain fields continue to grow apparently undisturbed. None of these problems directly affects the theme of this book, but it bothered my suspension of disbelief, especially as it was only necessary to kill off all the people, she could have left the animals alone, to get the situation she needed.
This book took the 1977 Hugo Award, and as well told exposition of one the major philosophical battles that man faces today and in the future, it deserved it. But it is a definite 'thinking' book, not one of action, grand drama, or deep psychology. Expect to do some internal reflection when you finish this book, and see how you stack up as an individual versus your place in and responsibilities to your surrounding society.
