Sons of Empire — Bill Willingham

The free Fables living in the mundane world have struck a decisive blow against the Adversary, destroying one of his most valuable assets at the very heart of his empire -- and setting the stage for an all-out world between the worlds in the process. Now, while the ruler of the Homelands licks his wounds and gathers his forces, the denizens of Fabletown have a rare chance to savor the brief peace their victory has brought them. Everyone, however, knows that this is just the calm before the storm -- and that even the winds themselves have to choose before it's over.
