Dune meets Wool in this high-octane quest through the void, where two eternal forces are about to collide in an epic showdown.
When The Sinker was a child, her home was destroyed by The Construct, a floating machine that consumes all in its path. To survive, she fled into the void, a seemingly infinite nothingness filled with floating, vertically stacked rocks. While most are afraid of traveling through this void, The Sinker is not. Some rocks are giant magnets, some rocks burn with eternal flame, and some are influenced by the presence of seemingly magical objects—anomalies that defy physical laws.

For half a lifetime, The Sinker has wandered the void on a quest for knowledge, for understanding, and for peace. But when rumors reach her that The Construct is near again, she knows fate has come full circle. With the help of Crooked Arm—the heir to a shattered throne who happens to possess the most powerful anomaly of all—the two of them set out on a mission to end the tyranny of The Construct forever.
