Things are changing. . . the discovery of the jump drive has led to massive expansion of human colonization. And a breakdown of the social order where old Earth might be obeyed.
One character is the only former naval man on one colony threatened by a ship for protection money. Two other characters were stranded by pirates among the other passengers, and find their rescuers as rapacious. One just is trying to escape her past as a Red, from Mars.
Conflict and troubles, involving a boarding party, a false recruitment pitch, a hint of unofficial interest, a discussion of mayors, an inexplicable attack, and more.
A jump back into the past for the Lost Fleet universe. The ending, while rounding this out, does point rather strongly at its trilogy status.
