Olympus One colony students Hal Leon and Akio Sato have made history. Their invention, a camera that images dark matter, has had its first successful test; but what it reveals may put human life on Mars in jeopardy. Hal believes that the strange animalistic silhouettes hidden in the dark matter web prove his theories. The wiry, inhuman forms appear to look to the sky at some invisible threat before they're wiped away by a wave of nothingness that resets the dark matter web to normal, until it all repeats again--a never ending cycle. That is, until something else appares in the dark matter web, and students and colonists alike start dying under mysterious circumstances. Can Hal and Akio figure out what's causing these grisly murders, and does the dark matter camera somehow hold the key to the mystery?
