The Shirukan aren't the only threat to the Starfire shard Raea bears. An alien enemy has awakened to reclaim the crystal that was theirs, and those last survivors of a war which nearly destroyed Inar'Ahben aren't afraid to kill anyone who stands in their way. An ancient monument to a mythical civilization on Earth may hold the key to stopping the new enemy, if the secret of its origins can be unlocked. Raea is running out of time to solve the most puzzling question of human history and resolve the conflict brought to Earth. If she fails, she may lose more than the Starfire.
