Following his success at the Grand Conclave on Earth Prime, Dave Brewster and his friends set out to expand the Free Society. However, all is not well in the galaxy. A Maklakar battle station is headed toward Earth. Mysterious ripples in space-time are confounding the Temporal Command. Agents from Predax and the Brotherhood are recruiting other planets to join their crusade against the Free Society.

Setting aside those challenges to help his Gallicean friends, Dave follows them on the Sojourn, an ancient ritual to remember the atrocities of the past. On the two planets in the Gallicea system, Dave learns of the past but also discovers the truth is often visible only to those willing to see.

Tears of Gallia is a story of friendship, perseverance, and faith. Will Dave be able to stop the Brotherhood from starting a galactic war? Can he survive a madman's attempts to kill him or strand him in the ancient past?
