Hungry Hollow is simply an ordinary creek winding through about a mile of ordinary forest and meadow somewhere east of the Rocky Mountains. But like all such places, it is also a vast and intricate web of life with extensions that reach around the planet, back into prehistoric time, and within to a teeming, bizarre microscopic world. In dozens of short, wonderfully imaginative chapters, A.K. Dewdney introduces us to the denizens of this world. We encounter a hackberry tree whose branches perfectly reproduce the taxonomic Tree of Life, learn how it would look and feel to shrink by stages to the size of an amoeba while swimming in a river, watch a toad win the lottery, and see the world of Hungry Hollow from the viewpoint of bears, earthworms, and even stones. This is an excursion into natural history like no other.

When The Planiverse ?rst appeared 16 years ago, it caught more than a few readers off guard. The line between willing suspension of dis- lief and innocent acceptance, if it exists at all, is a thin one. There were those who wanted to believe, despite the tongue-in-cheek subtext, that we had made contact with a two-dimensional world called Arde, a di- shaped planet embedded in the skin of a vast, balloon-shaped space called the planiverse. It is tempting to imagine that those who believed, as well as those who suspended disbelief, did so because of a persuasive consistency in the cosmology and physics of this in?nitesimally thin universe, and x preface to the millennium edition in its bizarre but oddly workable organisms. This was not just your r- of-the-mill universe fashioned out of the whole cloth of wish-driven imagination. The planiverse is a weirder place than that precisely - cause so much of it was “worked out” by a virtual team of scientists and technologists. Reality, even thepseudoreality of such a place, is - variably stranger than anything we merely dream up.
