Spoiler alert. In /The Three-Body Problem/, by Cixin Liu, a planet in the Alpha Centauri system is inhabited by an advanced alien civilization that evolved to survive the hardships related to the unpredictable effects of the three stars on the planet. Though able to survive, it comes at a great cost to their civilization (requiring them to “dehydrate” and hibernate for, sometimes, hundreds if not thousands of years) and eventually they hatch a plan to move to another habitable planet. Fortuitously they receive a message from Earth, from an astrophysicist who detests humanity and invites aliens to invade.

I found the rest of the book (and the two volumes that follow it in the series) to be very entertaining!
