Adrian Tchaikovsky - "Children of Time"

Amazing book about a broken earth whose civilization set out on large ships like Gilgamesh, trying to see the universe with human life.

Gilgamesh clashes with a planet that was terraformed, but a nanovirus aimed at speeding up monkey evolution, did this to porta labila, jumping spider. The world of spiders and the world of a desintegrating space ship are beuatifully told and intermeshed.
