Beloved, by Toni Morrison.
This book means so much to me. The relationships between women are forged differently than the rest, I swear. This book demonstrates that magic, and the profound links that tie us together. The power of memory, of trauma, of repressing moments that bring us pain, and generational trauma. So many emotions, captured flawlessly in a book that illustrates a flawed woman in a difficult world. I recommend this, as well as everything else in Toni Morrison's corpus of work.
