All These Worlds. Dennis E. Taylor

"All These Worlds" is the third and culminating part of the Bobiverse series, in which humanity finds itself on the verge of survival, and an army of artificial intelligences - copies of Bob - is fighting for the future of galactic civilization. The novel combines large-scale space opera, scientific concepts and philosophical questions about the nature of consciousness, freedom and responsibility. After decades of colonizing space, the Bobs have made significant progress, but now they face their most dangerous challenge - the return of a cruel alien race that threatens Earth and all human settlement.

This is a dynamic, multifaceted story, where political conflicts, personal dramas and strategic battles are intertwined in a tense finale to one of the most popular modern science fiction series.
