I found this book completely by accident and had not even been aware that 'Beggars in Spain' was part of a triology, I was merely looking for other great books by Nancy Kress. But what a find it was! This is a great book and a great follow up to 'Beggars in Spain'. I love the way how Nancy has taken genetic enginering to the next level and can't wait to read the third book.
An excellent sequel to Ms Kress' Beggars in Spain novella.A believable future world and developments from the original premise of genetically altered embryos who would not require sleep. Nancy Kress is a worthy colleague of writers such as Peter F.Hamilton and Joe Haldeman. Cannot recommend it too highly.
