Ceres — L. Neil Smith

Nominee for the 2010 Prometheus AwardIn the 22nd century people have spread into the Solar System. Born and raised in a twentieth of Earth's gravity on the asteroid Pallas, young skater Llyra Ngu is grimly determined to compete and win on mankind's homeworld -- an ambition that many say will cripple or kill her. Her older brother Wilson is equally set on quitting his job as a surveyor's apprentice to become an asteroid hunter, a calling fraught with the promise of fabulous riches and the danger of sudden death. He will find a full share of romance and disappointment, love and loss, and pursue the asteroid hunter's holy grail, the legendary Diamond Rogue. Llyra's training will require years, and a journey that will take her to Ceres, at one tenth Earth's gravity, where her father bosses the Ceres Terraformation Project, to the one-sixth gravity of the Moon, to Mars and one third gravity, and finally to Earth. Along the way, she will survive jealous rivals, a hostile press, terrorist attacks, and the hijacking of a spaceliner in order to achieve her goal. In the end, Llyra and Wilson will hear the call of the stars, themselves.
