I have been fortunate enough to read this upcoming debut early, and I am so very grateful! The novel follows Addie and Eva, two souls living in one body. Souls are expected to settle at a young age, picking one to dominate while the other fades into oblivion. In Addie and Eva's case, neither girl wins out and the girls live with Eva's identity still present, but secret. The way dialog is handled between these two girls is fascinating, often treated like an internal monolog. Where most people would say "I," they say "we." I want to say this is a story about sisters, but it's not. Not really. Addie and Eva share an even tighter bond, and their relationship in this book is simultaneously beautiful and claustrophobic. They are never one without the other.
