A covert plot to explore an uncharted dimension goes awry when a rocket explodes mid-flight. While families mourn their beloveds, the astronauts find themselves in The Split, a vast void in space. Harnessing the crew into his mind, D'Rozen attempts to keep alive those under his watch, but falling in love with Tarryn hampers his objectivity, as does the connection he shares with his brother Estén back on Clatham, who realizes all those rocketeers are still alive.

While corrupt politician Hanley continues manipulating the populace, Estén joins forces with Rist, whose wife Kasha was on the doomed flight, as well as Holtz, a former astronaut aware of Hanley's illicit scheme. Tarryn's husband Lee senses her presence, yet is unaware that Tarryn went into space pregnant. And according to Estén, she still is.

Families are divided by political intrigue as those inside D'Rozen's mind ache for release. Yet no one is safe as the depth of Hanley's treachery is revealed. Can D'Rozen protect his crew, as well as himself, or are all still on a collision course with destruction?
