Book 50: A Brief History of Time (Hawking)

Interesting stuff.

Book 49: Pushing Ice (Reynolds)

OK SF. Some cool ideas, but protagonists were annoying power-loving heirarchs.

Book 48: Half a Crown (Walton)

Very good conclusion to the series.

Book 47: The Prefect (Reynolds)

Very good standard SF. No singularity: no real AI.
