This book was not as I expected, but in this case that's a good thing. First and foremost: the bulk of this book is not actually about space, but rather the life story of Ollie Ines recounted in the large volume of time he has available during a long journey in space.
While I did enjoy the chronicling of the space travel, and the impact it had on the greater story, my favorite part was undoubtedly the narrator's life outside of the mission. The author, Cecile Pin, does a really nice job telling a cozy and calm story that manages to retain interest, and it was easy to return to multiple times a day to read. Especially closer to the end of the book, I found myself upset with the main character for the decisions he made — but these decisions enabled Pin to explore some highly emotional and complicated interactions between characters which not only allow for Ollie's reflection but for the reader as well. It definitely forced me to think through aspects of my own life, and how I believe I'd act if placed into the same circumstances he was.
Philly, who you're introduced to early in the story, is my favorite character. She reminds me of several friends of mine growing up, none of which I'm in contact with anymore but nevertheless recall for the same "strange" mannerisms they had. She would definitely have been made fun of at the schools I attended, but she could easily have been a great friend. Ollie and Philly interacting with one another was the source of the most emotion for me in reading this, and that contains both pleasant and difficult feelings. I know they aren't real, of course, but I feel for Philly nonetheless.
On the flipside, Mark is my least favorite character. He's written well — well enough to instantly make me think of irritating tech billionaires indulging themselves throughout their lives by throwing money around to get whatever (and whomever) they want - and he reminds me a lot of a specific billionaire who is particularly infuriating and owns a very similar start-up to Mark's. (Hint: his last name is the same length, and both starts and ends with the same letters, as the fictional character's first name. Was that intentional?)
While it's not particularly lengthy, Celestial Lights is a worthwhile read and I can easily recommend it to other readers. Think of this as a "realistic fiction — science fiction hybrid" title, if you will.
Thanks to NetGalley and the publisher for the opportunity to enjoy this book's ARC ahead of release. My review is my honest opinion of the book and is not affected by my selection to receive an early copy. All opinions expressed herein are my own. I will likely purchase a print copy of Celestial Lights when it officially releases.
