Ann Leckie’s Imperial Radch series concludes with Ancillary Mercy. A person is discovered in the Undergarden who should not exist, who may represent a ship that has been hiding from Anaander Mianaai for centuries. But just as new information begins to provide the pieces of the puzzle, forces arrive in the outskirts of the system, and they don’t appear friendly.
A powerful investigation of the challenges of truly reaching for the stars. Kim Stanley Robinson asks, “What would it really be like if we tried,” and then comes up with some answers, not all of which are pleasant to consider. While you can (and people have) poke holes in some of the science and assumptions, this book goes further and deeper into the underlying difficulties of sending people into space for over a hundred years, and leaving behind the cradle from which we came.
