Jim Grimsley's previous science fiction novel, "The Ordinary, " was named one of the Top Ten science fiction books of the year by "Booklist" and won the Lambda Literary Award. His novels and short stories have been favorably compared to those of Ursula K. Le Guin, Jack Vance, and Samuel R. Delany. Now Grimsley returns to the richly complex milieu of "The Ordinary" with a gripping tale of magic, science, and an epic clash between godlike forces. Three hundred years have passed since the Conquest, and the Great Mage rules over all of humanity, even as cybernetic links connect the varied worlds of the empire. Vast Gates allow travel from one planet to another, across unimaginable distances. Choirs of chanting priests maintain order, their songs subtly shaping reality, while the armies of the empire have known nothing but total victory for centuries. But on the planet Aramen, where sentient trees keep human symbionts as slaves, a power has arisen that may rival that of the Great Mage himself. Hordes of unnatural creatures rampage across the planet, leaving death and destruction in their wake. An inhuman intelligence, cruel and implacable, meets the priests' sung magic with a strange new music of its own. The Anilyn Gate is shut down, cutting off Aramen from the rest of humanity. The long era of peace is over. Now a handful of traumatized survivors must venture deep into a hostile wilderness on a desperate mission to uncover the source of the enemy's powers. And the future of the universe may depend on the untested abilities of one damaged child. . . . "The Last Green Tree" is a worthy successor to "The Ordinary" and a compelling saga in its own right.
