In the unending expanse between universes... the crew of the great bronze airship Kubla Khan are lost. The path they have been following is gone and they have no idea how to get home. But amongst the swarms of blood thirsty alien creatures which haunt this deadly place, there are worlds so very like their home, which also need help and protection from the monsters. On another world which could so easily have been their own, the crew of the Kubla Khan give battle once more to the creeping horde of invaders from the Expanse, but while they struggle against the monsters, other enemies, with human faces, are also plotting against them. By a Blue and Crimson Light is the second volume in the 'Glass Darkly' series.
