The Unseen World by Liz Moore. This book shook me to the core. It’s a long read. I took a break in the middle of it to absorb a major twist, and came back to it a few days later to finish. Its story is detailed, delicate, prodigious, thoughtful, and careful in its telling. Secret identities, mental illness, academia, family history, science/math/tech, and longing for truth and family.
