       "\"Here is the novel that will be forever considered a triumph of the imagination. Set on the desert planet Arrakis, Dune is the story of the boy Paul Atreides, who would become the mysterious man known as Muad'Dib. He would avenge the traitorous plot against his noble family--and would bring to fruition humankind's most ancient and unattainable dream.A stunning blend of adventure and mysticism, environmentalism and politics, Dune won the first Nebula Award, shared the Hugo Award, and formed the basis of what it undoubtedly the grandest epic in science fiction.Before The Matrix, before Star Wars, before Ender's Game and Neuromancer, there was Dune: winner of the prestigious Hugo and Nebula awards, and widely considered one of the greatest science fiction novels ever written.Melange, or 'spice', is the most valuable - and rarest - element in the universe; a drug that does everything from increasing a person's life-span to making intersteller travel possible.

Although it is almost completely without water, Dune is a planet of fabulous wealth, for it is the only source of a drug prized throughout the Galactic Empire. The Duke and his son, Paul, are expecting treachery, and it duly comes - but from a shockingly unexpected place. Then Paul succeeds his father, and he becomes a catalyst for the native people of Dune, whose knowledge of the ecology of the planet gives them vast power. They have been waiting for a leader like Paul Atreides, a leader who can harness that force . . . DUNE: one of the most brilliantr science fiction novels ever written, as engrossing and heart-rending today as it was when it was first published half a century ago.\""

       "\"Winning will make you famous. Losing means certain death.The nation of Panem, formed from a post-apocalyptic North America, is a country that consists of a wealthy Capitol region surrounded by 12 poorer districts. Early in its history, a rebellion led by a 13th district against the Capitol resulted in its destruction and the creation of an annual televised event known as the Hunger Games. In punishment, and as a reminder of the power and grace of the Capitol, each district must yield one boy and one girl between the ages of 12 and 18 through a lottery system to participate in the games. The 'tributes' are chosen during the annual Reaping and are forced to fight to the death, leaving only one survivor to claim victory.When 16-year-old Katniss's young sister, Prim, is selected as District 12's female representative, Katniss volunteers to take her place. She and her male counterpart Peeta, are pitted against bigger, stronger representatives, some of whom have trained for this their whole lives. , she sees it as a death sentence. But Katniss has been close to death before.
