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!

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.

I love a well-written time travel story. This one had similar vibes to The Ministry of Time or the Time Variance Authority in the show Loki with a dedicated organization devoted to policing our timeline for anomalies. Although familiar, the book had enough inventive storyline to keep me interested - especially as it jumped far in the future to colonies on the moon! It inspired lots of good existential thinking.
