I finished reading The Dark Forest by Cixin Lui in February. The Dark Forest is the second volume of a trilogy. The third book--Death's End--will be published in September.
Last year, I read the first volume of the trilogy: The Three-Body Problem. It won the 2015 Hugo Award for best novel. The trilogy was written in Chinese and translated to English.
In the story, Earth is reeling from the revelation of a coming alien invasion. The aliens are on their way to Earth, but won't arrive for four centuries. A number of countries and organizations are working on long range plans and strategies for repelling the invasion.
I read science fiction for ideas. This book actually contains an interesting idea: hunters in the dark forest. Unfortunately, the author only starts to explore this idea at the end of a long book.
I didn't really enjoy this book. It felt like a couple of different books mashed together. There were long sections that I struggled through. Although I don't recommend this book, I will probably read the third book in the trilogy to see how the story turns out...
