This is a Three-Body Problem Paraquel that adds some interesting ideas and reveals a few things to understand a bit more about Yun Tianming and everything that happened during-after Death's End. Here we also confirm how a useless character Cheng Xin is. If you disliked her in Death's End, this book in one page will increase that feeling.
In the other hand, the book leaves the usual SF and Physics approach and plays more with an Ultra Hyper Dimensional Universe of things (some people are considering it Fantasy), and I don't really know how to feel about it.
There is a pretty nice reference to Asimov's Foundation as well.
In a nutshell it's not in the same quality as the original trilogy but it is truly worth a read.

Pd: The English version of this book is coming out in a few months but I'm glad to found out that the Spanish version was already on the bookstores since last year.

Excelente recuento histórico de la era pre imperial de Roma. Desde Rómulo y los primeros reyes hasta las conquista de Grecia en las batallas macedónicas, alrededor de unos 140 años antes de cristo.

El libro relata de manera entretenida las diferentes guerras que enfrentaron los romanos desde sus inicios, pero no solo eso, sino que también nos brinda una detallada descripción de su armamento y estilo de combate en aquella época, como también de alguno de sus primeros hitos de ingeniería y de la estructura social que gobernaba a la ciudad.

El tiempo abarcado incluye además de su legendaria fundación, y las intermitentes guerras con alguno de los pueblos inmediatos como los Etruscos y Samnitas, las de Pirro y su imperio helenístico, como también el periodo de guerra contra Cartago y Aníbal.

Lo más decepcionante que puedo decir en contra y que definitivamente dañaba un poco la lectura es que el autor en ciertas ocasiones no usa a.C  o d.C según convenga, sino que, por el contrario, escribe la fecha tal cual, ejemplo,  año 103. En ese punto vas intuyendo que quiere decir a.C, pero se vuelve fastidioso el cambio.

A pesar de eso, el recuento que da Javier Negrete de esta parte de la roma antigua es bastante satisfactoria y elegante. 

I sort of liked this book, but it was too short on each topic that by the end it barely made sense to me reading it when most of the things are 2 seconds away on a web search. Actually, that was what I did for basically every chapter, as a way to know what else is missing and also explains why it took me longer to finish it. It does not go deep on anything and give you a very surface level understanding of the universe.

I guess that was the point of the book at the end, and I am being too picky here. Despise my rating, it was entertaining and enjoyable, just that I was expecting a bit more substance.

If you have never come across the Fermi paradox then this book has a fantastic way to explain one of its solution. The dark forest hypothesis.

I consider this one of those slow but great books in speculative fiction. Much better than the previous one in my opinion due solely to its sheer scale.

The aliens found in the previous book, called Trisolarans, are coming and will reach the planet in roughly in 400 years. They become substantially dangerous as they are able to send subatomic particles that allows them instant knowledge of all human information, leaving us with barely anything to protect us as everything we can think of is already known by them and therefore end up sabotaged. The only thing they cannot know is what is inside peoples mind.

How do humans deal with Trisolarans with just that is the main plot of the book .

There are too many things here that are utterly insane. Reading the book for the first time was quite an experience. If you like mind bending ideas, plot twist, don't care much about the characters and are fascinated by old school Sci Fi, then this book is a must read.
