From BooklistIn a post-ecocaust future, Earth's natural biodiversity has been decimated. Millions are dead, and the rest have been shuttled into clades. When Rigo, who is working his way up from the poverty of the San Jose clade, is invited to travel to the asteroid being colonized with the aid of the warm-blooded plants that he has been working with, he knows that if he wants to move up in the corporate world, he must go. Concurrently, his social-worker girlfriend decides to hide her newest case, Ibrahim, a child suffering clade-incompatibility, at Rigo's mother's place when the secret police come for him. She and Rigo discover that Rigo's reclading somehow provides the pherions Ibrahim needs to survive and that there is a conspiracy to maintain the status quo through slave pherions. Rigo has fallen into the middle of this plot and also into position to help start the revolution of reclaiming the biodiversity of the past. A fast-paced read animated by an engrossing, nervous energy. Regina SchroederCopyright © American Library Association.

Budz may welll have created a new genre: biopunk."—Kevin J. Anderson"A remarkable book.... Scientific, tense, gritty, and thoughtful, Clade pulls you into a bioengineered tomorrow that may come startlingly true."—David Brin
