If only I read your post properly. Yes, it is. Not a trilogy, just a lonely sci-fi book, and it was mentioned here before, but have you read Tchaikovsky's Children of Time? There is apparently a successor in the pipeline for next year. Also, you could check out, if you haven't already, the Ender books (supposedly young adult stories, but the second book is definitely too heavy for teenagers, if you ask me) or Sylvain Neuvel's trilogy (Sleeping Giants, Waking Gods, Only Human). The latter is not really a meaty sci-fi trilogy, but a great read nonetheless. Sorry I cannot recommend more, I'm not an avid sci-fi reader.
