Police officer Dora Henry is investigating the bizarre murders of three geneticists. Meanwhile, strange things are happening everywhere she turns. Weeds are becoming trees; trees are becoming forests. Overnight, a city is being transformed into a wild and verdant place.

And, strangest of all, Dora can somehow communicate with the rampaging flora.

A potential civilization-ending catastrophe is in the making. The nearer Dora gets to a murderer--and to the truth--the more seemingly disparate events begin to entwine. And the answers she seeks today to the salvation of humankind may lie in afar distant future. . .one which is suddenly much closer than anyone imagines.

An exhilarating and enchanting novel that deftly combines fantastic invention with insight and a social conscience, from one of the most lyrical and important voices in contemporary speculative fiction.
