After the events of Infinite Velocity, the crew find themselves in trying circumstances. Separated from each other Skyler and RK struggle to fix two very different situations.
The Foxglove Corporation has taken back control of Velocity from Skyler while a shuttle of refugee children depend on the young engineer for guidance and protection. Both find themselves battered and nearly broken from their fight with the Requiem. But healing physically is only half the battle. In order for a new day to begin, Skyler and RK will have to learn how to let the sunset on who they were and accept who they must become.
However, the problems of our intrepid heroines pale in comparison to the looming danger facing Earth. A new and powerful threat creeps into our solar system with its sights set on the human race at large.
Can differences be set aside long enough to save humanity or will the divisions we create be the end of everything we know?
