Earthward

"The Mercury Six are sent on a standard supply run, but return to find Mercury adrift, and their respective parents missing. The quest to piece their family back together will take them to the edge of known space and back, with the Armada, the Council and Space Pirates, all in hot pursuit. The one thing everyone wants, everyone needs, is the secret project the parents of the Mercury Six were working on: the discovery of Earth" --author's Kickstarter.
