Historical: Liberation of Terra, Volume 1 describes the early years of the civil war that would ultimately bring about the final end of the first Star League. Covering the fighting from the coup itself to the bloody campaign for the Terran Hegemony, this book provides a hard look at the closing years of the Star League Era, and the fateful decisions that would eventually pave the way for centuries of Succession Wars to come.
