The Glittering Cage
by Richard Ireland
The Longways broke him, but Rift was already cracked. Trapped as a child in the glittering cage of autism, his past life is cut out as a brutal cure on the world of Edria.
An impurity in a pure place, he is the last hope for its dying god Setti. Manipulated and empowered by her, he can choose to save Edria when she dies. But it is a choice between sacrifices.
