Polostan

By Neal Stephenson.

I'm unsure about this book. It's a good read. Chapter by chapter it is very compelling. Dawn is a fantastic character. And then it just ends. Sure, she is in a bit of a predicament, but there is little overall mystery and there have been so many twists and turns along the way that I don't doubt that Dawn will escape.  

Elsewhere online, I see that Stephenson is planning to start a series with Polestan being the first book.

Death's End

By Liu Cixin.

A good end to the Three Body Problem trilogy. The book is an enjoyable read. If I have any beef with the book it's that Cixin wanted to write more about the books theme's, than about the plot. At some point, about 2/3rds of the way through the book, the villains, the Trisolarians, just leave and they are never really heard from again. We never learn much about them. Of course the Trisolarians were never the point of the story. The point is to dive into the harsh realities of cosmic sociology, where civilizations must remain hidden or risk annihilation in a ruthless, Darwinian universe.

The Last Thing He Told Me

By Laura Dave.

A fun and readable family mystery. After his employer is accused of fraud, a father sends his wife and his daughter cryptic messages and then vanishes.
