The sequel to Children of Time carries on with the same tone and atmosphere, building out the time-, space-, and biology-spanning ideas established in the first volume. This is Big Idea scifi, but with the well-crafted characters that are often the weak point of such works.

The world building in both Children books is superb. It succeeds in providing the narrative tools to establish continuity across vast stretches of time and distance. And that continuity creates a very compelling story that grapples with ideas of communication and collaboration among truly alien species. All anchored by relatable characters seeking solutions to Life-altering encounters. And sometimes finding them.

Highly recommended!
