Phenomenal! This was a fantastic science fiction with horror elements debut with complex worldbuilding. Hoffman does not hold the reader's hand when introducing them to this world, which can be confusing at first, but it evens out as you read. AIs/quantum computers have become godlike and have set limits for humanity. Meanwhile, energy has mysteriously started disobeying the laws of physics and creates chaos. 

I really enjoyed the characters and thought they were pretty well developed. There aren't a lot of physical descriptions of the characters, but the author does a good job of describing the world and scientific concepts. The main character is a multifaceted queer female scientist with Autism, and I thought she was beautifully portrayed. The novels also explores what makes us human, mental health, and what it means to be different.

The last half of the book is a lot to take in because of the fast paced plot and because we are still learning about the Outside, but it is definitely thought provoking and will stick with me. I was so invested that I jumped straight into the next book, The Fallen.
