Jarra never wanted to be a celebrity. All she ever wanted was to gain some respect for the people left on Earth: the unlucky few whose immune system prevents them from portaling to other planets. Except now she's the most famous Earth girl in the universe - but not everyone in the universe is happy about it, nor the fact that she has found love with a norm. Jarra's actions have repercussions that spread further than she ever could have imagined, and political unrest threatens to tear apart the delicate balance of peace between humanity's worlds. On top of everything, the first alien artifact ever discovered appears to be waiting for Jarra to reveal its secrets. But to do so, she must somehow find a way to leave Earth - or else the alien artifact will be lost forever. Is there a way for Jarra to travel to another planet? Or is her destiny only to look to the stars - but never to reach them? From the Hardcover edition.

This monograph contains an overview of classical dynamics, providing a solid basis on which to build an understanding of the theory of interplanetary flights. The treatment of the topic is based on both historical and topical perspectives. The theoretical development is illustrated with a number of practical examples, bringing to bear the author's experience gained from working on the Soviet space programme. Many examples are taken from current space missions - new data is included on the Shoemaker-Levy 9 comet, the flight of ULYSSES over the Solar poles and the Voyager's tour of the solar system.

Edge of Flight is the toughest rock-climbing route Vanisha has ever faced. She has one last chance to conquer it before she moves to Vermont to start university. University is a sore point for Vanisha, who yearns for a career in the outdoors but feels pressured by her mother to earn an academic degree. Trying to put school out of her mind, she heads to the Ozark Mountains of Arkansas with her buddies Rusty and Jeb for a final weekend of climbing and camping. Deep in the woods, they stumble on an illegal marijuana plantation, and the gang of bikers who guard it. When Jeb is shot by the bikers, Vanisha alone must get help—and to do so, she must climb Edge of Flight. As she confronts her insecurities on the cliff face and in the woods, Vanisha gains a new resolve and the self-confidence to choose her own path in life.
