The 2nd book in the Red Rising trilogy, this follow-up brings the story in an un-formulaic direction. Somehow this book was able to make the switch from personal battles to space battles without skipping a beat all while keeping motivations realistic.

Great introduction to graph databases – specifically Neo4j and Cypher. The approach in this book was helpful - iterating on problems and showing how one potential solution brings up new problems if you don't think it through.
