Apocalyptia (Apocalyptia #1)

A star. It hadn't been a war, a government takeover, or even an earthly disaster. It was a star that had ended the world, with Crystal right at the heart of it, and all that stood between her and instant death was a desk. Her chances at survival were slim, but she did it. Despite her luck, the world did not receive the same fate. With a man she's only just met, Crystal must continue to survive. Determined to reinstate her old way of life, Crystal must come to terms with more than just physical loss, but the chance of losing herself in the process.
