While I liked Greg Egan's other novels, Diaspora didn't grip me at all and was very hard to get through. The fact that it revolves around an advanced species that can change itself to any degree it wants to made it hard to feel sypathy with any of the characters. The beginning was really strong, describing how their civilizations and personalities are formed. But after that, to my feeling the book consisted only of excalating physicsbabble and arbitrary personality changes, and this escalation continued right upon the not quite satisfying end.
Das ist mir dann doch zu harte Hard Sci-Fi ^^
