This book lives rent free in my mind, and it inspired me to reread The Glass Hotel. I love a book written out of order or with multiple narrators whose perspectives we have to balance. St. John Mandel places scenes so familiar to us we can inhabit them inside of fantastic plots that remain with you in scenes as vivid as Toni Morrison’s.

A quiet, poignant, meditative book. I'm amazed at what the author accomplishes in under 300 pages. She pulls together deft, evocative of sketches of 4 characters across 4 time periods while also exploring deeper themes including family, purpose and the meaning of reality. I didn't love it quite as much as Station Eleven but I still loved it!

I wasn't so sure that I was even going to enjoy this book in the beginning. It felt so slow and unimportant. But it's a short book, and one I had preordered because it was one of my most anticipated novels of the year. I also had friends who were early readers and gave it amazing reviews. So I knew I was going to finish it no matter what. I am so thankful that I did.

Emily St. John Mandel, you are a genius. I don't know how you were able to convey such profound thoughts, feelings, and the whole meaning of existence in 255 pages. I don't know where you found the language to make this story so beautiful and heartbreaking and hopeful. But I am so happy you did and now this beautiful little book exists and I will be recommending it to so many readers.

Predictable ending. Not a fan but don’t hate it. Easy read. Lack of depth to the characters and world. Cheap “tricks”. Cringy author insert character Olive. Interesting complex ideas with the surface barely scratched.
