There's a lot to unpack with this somewhat complex story, but that'll be much easier with the book in-hand. This is a sci-fi story that's been viewed in the past as "unadaptable," but it made for a thrilling ride when it hit Netflix as an adaptation from Game of Thronescreators David Benioff and D.B. Weiss, along with True Blood's Alexander Woo.

In a nutshell, this first book explores a past, present, and future where Earth comes into contact with an alien civilization from another Solar System-like galaxy with three suns, a representation of the "three-body problem" in orbital mechanics. The phrase refers to predicting the motions of three bodies (in this case the three suns) that interact gravitationally, like our system's sun, earth, and moon. Isaac Newton was the first to study this problem and realized it was very difficult to solve – and it's pretty complicated here, too.

If all that sounds like a fun ride despite the complexity, grab the book while it's still on sale for just $8.
