Keith Laumer created the Bolos and the series and David Weber has taken over the tasks of putting out new tales about the self aware treaded behemoths. This book is about Lazarus and Maneka, the sole surviving human and Bolo of the Dinochrome Brigade's 39th Battalion. The tank is being paired up with a new operator and is being shipped as support as part of a new, secret colony. Unfortunately, the colony ships have been discovered and are being followed by a Melconian armada. Through a suicidal effort, all of the Melconian ships are destroyed but one and that ship begins to track the surviving human colony ships right to planetfall. The humans hope to establish a colony unknown to the Melconians because the Melconians are winning the war and are forecast to destroy humans totally. For their part, the Melconians have utilized all of their resources following the colony ships and have dedicated themselves to destroying this before it can even get a foothold. The only thing standing between the humans and the Melconians are Maneka and her bolo Lazarus.
