Remaking Eden is a fascinating exploration of the future of reprogenetic technologies - a cautiously optimistic look at the scientific advances that will allow us to engineer life in ways that were unimaginable just a few short years ago. Indeed, in ways that go far beyond cloning, and that are at once more thrilling and more frightening.

Could a woman give birth to her identical twin sister? Could a child have two genetic mothers? Could a man become pregnant? Could parents choose not only the physical characteristics of their children-to-be, but personalities and talents as well? Will genetic enhancement ultimately change the very nature of our species? The answers will excite some and alarm others. Silver demystifies the science involved in all these possibilities, calmly and efficiently dismantling our preconceptions and misconceptions.

Throughout, he examines the profound ethical questions raised by these new technologies. Yet he reminds us that the desire both to have children and to provide them with all possible advantages in life is a uniquely powerful force - a force, he suggests, that will overcome all political and societal attempts to curb the use of reprogenetics.
