Andy Weir does it again with this thrilling sci-fi adventure! The protagonist, Ryland Grace, wakes up alone on a spaceship with no memory of his mission, and the gradual revelation of his purpose is masterfully done.

The science in this book is both accessible and fascinating. Weir's ability to explain complex astrophysics concepts in an engaging way reminds me of Carl Sagan's work. The relationship between Grace and Rocky is the heart of the story - one of the most unique and touching alien friendships I've encountered in fiction.

While I enjoyed The Martian more, this is still an excellent read with plenty of humor, problem-solving, and high-stakes drama. The ending was particularly satisfying and unexpected.
