As their grandmother slides into dementia, an unnamed narrator begins to ask questions - to fill in the gaps, to resist the silence that shrouds their family. Childhood memories resurface, revealing a path into the past, winding back through generations. This matrilineal line leads toward nature, witchcraft, freedom. Could this be where they belong? What follows is an astounding quest for liberation - from generational trauma, class identity, the limits of language. It's a search for other forms of knowledge and traditions, other ways of becoming. Bold and expansive, Blood Book is an unforgettable reckoning with the past, and a mesmerising exploration of who we are.
