    For hundreds of years, the danger of collision has been ignored as mere crackpot theories, until now, and now it's too late. Collision is a short story commissioned by Vanquish Motion Pictures for development in film and television, and is the first in a series of character-rich, mystery-driven science fiction grounded in science fact.

    A deadly challenge. The fate of the world is on Astra’s shoulders.Twenty-five-year-old Astra Ching has never sought the spotlight. So when a mysterious black orb appears with a challenge for Earth and selects her to compete in its strange—and very public—game, she’s not pleased to find herself a sudden superstar.The rules are bewildering, and there are no second chances for losers. Yet while Astra fights to stay alive and save the world from imminent destruction, the people of Earth are more interested in tabloids and gossip, like whether or not she’s engaging in a scandalous love affair with a fellow contestant . . . or the mysterious alien known only as Eleven.In her struggle to survive, Astra forms tentative alliances with a handful of trustworthy friends. But as the global gossip seeps into the game and contestants are eliminated with each round, Astra’s celebrity threatens to become infamy and the line between friend and foe blurs.Will she emerge from the arena a hero, or just another headline?
