Yashika and Philanthora are Needles, beings with the ability to stitch and unstich the very fabric of the universe, to create pathways between worlds and bridge impossible gaps. They were married, always together, playing the Invisible Chords of the Weave together. Until the great Merchant city of Idlethen fell to the wrath of the fanatical Second Empire. They were torn apart, cast across the worlds of the Weave. Now, among the fear, fire and blood of the Empire's wrath; can they find their way back to each other? Atonement is a slave soldier, a human trapped behind a mask as much as they are trapped behind their rifle. But the invasion of Idlethen presents something different, something new. What will Atonement find in this strange new city?
