After Children of Time
Spin by Robert Charles Wilson
If Children of Time taught you to empathize with alien minds through rigorous evolutionary science, you're ready for the next level of cosmological horror. Watching spider consciousness ascend gave you that vertigo of deep time—now imagine Earth trapped in a membrane where every second outside equals a hundred million years within, and incomprehensible forces architect humanity's fate with chilling indifference. Same intellectual rigor, same generational scope, but here we're the desperate species.
