The family tree

The once fertile Earth of Dora Henry's childhood has been undervalued and overdeveloped. Now nature, apparently, has decided to fight back. 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.
