"A Tom Doherty Associates book."

When proof surfaces that humans may not be alone, a mission to build a telescope on the side of the moon claims lives and reveals a secret that will forever change humanity. Just 30 light years away, a planet similar to Earth--one that could possibly contain life--is the focus of those building a telescope to get a better look. What nobody realizes is just how dangerous building the Farside laboratory will be. The Moon may hold its own secrets.
