Children Of Time 3 Book Set by Adrian Tchaikovsky

Across vast timescales, a failed terraforming experiment and the fragments of humanity set off an epochal drama in which uplifted nonhuman intelligences—most notably complex social spiders—alongside diverse AIs and stranded human survivors build, lose, and reshape civilizations; the trilogy follows their conflicts, fragile alliances, and moral reckonings as they confront questions of identity, memory, evolution and what it means to survive and coexist in a harsh, scientifically detailed space-opera landscape.
