About the book

Inside Book 7

A train is rolling west with everything John Kerrigan has left to lose on board.

He isn't on it.

Between him and the end of the line is a thousand miles of dead country, an enemy who has waited years to say a name out loud, and something in a sealed car that should not be alive.

He used to be a soldier. Now he is only a father.

Reading order: this is Book 7 of the saga. If you are new here, start with Echoes of the Dark Sun.
