"Tipping Point for Planet Earth explains why Earth is headed for a tipping point, a change so fast, dramatic, and unexpected that humanity will reel at the consequences. Midway through this century, there will be more than nine billion people on the planet. Already we are using most of the arable land that exists and overfishing the oceans. Water, too, is becoming scarce in many places. The services that humans depend upon--like a supply of clean water, food production, and protection from disease--are subject to dangerous threats as well. We can still keep humanity moving forward by ensuring that the negative changes that are accumulating do not outweigh the positive ones. Tipping Point for Planet Earth offers sensible solutions to our most pressing problems. The grand challenge of the 21st century is to change the endgame from one that looks like a train wreck, to one that sees the train carrying us all into a bright future"--

In Dragon's Kin, bestselling author Anne McCaffrey did the unthinkable: for the first time ever, she invited another writer to join her in the skies of her most famous fictional creation. That writer was her son, Todd McCaffrey. Together, they penned a triumphant new chapter in the annals of the extraordinarily popular Dragonriders of Pern. Now, for the first time, Todd McCaffrey flies alone. And Dragonsblood is proof that the future of Pern is in good hands. After all, dragons are in his blood. . . .Never in the dramatic history of Pern has there been a more dire emergency than that which faces the young dragonrider Lorana. A mysterious fatal illness is striking dragons. The epidemic is spreading like wildfire . . . and the next deadly cycle of Threadfall is only days away. Somehow, Lorana must find a cure before the dragons--including her own beloved Arith--succumb to the sickness, leaving Pern undefended.The lyrics of an all-but-forgotten song seem to point toward an answer from nearly five hundred years in the past, when Kitti Ping and her daughter Wind Blossom bred the first dragons from their smaller cousins, the fire-lizards. No doubt the first colonists possessed the advanced technology to find the cure for which Lorana seeks, but over the centuries, that knowledge has been lost.Or has it?For in the distant past, an aged Wind Blossom worries that the germs that affect the fire-lizards may one day turn on larger prey--and unleash a plague that will destroy the dragons, Pern's only defenders against Thread. But as her people struggle to survive, Wind Blossom has neither the time nor the resources to expend on a future that may never arrive--until suddenly she uncovers evidence that her worst fears will come true.Now two brave women, separated by hundreds of years but joined by bonds transcending time, will become unknowing allies in a desperate race against sickness and Threadfall, with nothing less than the survival of all life on Pern at stake.From the Hardcover edition.

"Linguistic Geometry (LG) is an approach to the construction of mathematical models for large-scale multi-agent systems. A number of such systems, including air/space combat, robotic manufacturing, software re-engineering and Internet cyber-war can be modeled as abstract board games. These are games with moves that can be represented by the movement of abstract pieces over locations on an abstract board. The purpose of LG is to provide strategies to guide the games' participants to their goals. Traditionally, discovering such strategies required searches in giant game trees. These searches are often beyond the capacity of modern and even conceivable future computers."--BOOK JACKET.

And Shan Frankland—once a police officer, once human, now something much more—must decide where her loyalties truly lie: among the gethes, on a planet she once called home, or here, where a dying species presents her with a new and unexpected crisis.
