For readers of Megan Nolan and Sheila Heti, a mesmerizing Borgesian literary debut about the frayed borders between our bodies and minds.

Ada lives a solitary life. She spends her days in her London apartment building's swimming pool, occasionally visiting with her cousin Francesca and meeting her friends, each of them chatting, drinking, posing invitations Ada ignores. Ada's parents are recently divorced after her father became a bodybuilder: he spends his days at the gym, which is crowded and bright, warm with human proximity, infrequently calling to express minor concerns around his daughter's well-being.

When she meets a man named Atticus by the pool, Ada immediately feels an intimate connection between them: they share a life, in a way she can't explain. Little by little, Ada's estrangement from her familiar surroundings and from reality widens, as though seeing her reflection through a mirror, pieces of it falling away. After her mother entreats Ada to join her on a remote Greek holiday, Ada is jolted out of the physical world and into a new, artificial environment, one that a mysterious and potentially otherworldly force has created and designed for her. As this brilliant first novel pivots with masterful effect into the surreal and speculative, we move through Ada's experiences of life like spokes on a wheel, profoundly surprised by the enduring mystery of our existence, and of our relationships with ourselves and others. When a person's life, in the odd space between mind and body, is inherently one of isolation, are our connections with those around us merely projections of ourselves? And if not, where do they come from?

Albertine Clarke transforms the speculative into an entirely singular experience of deep interiority. The precision, subtlety, and confidence of her writing is nothing short of astonishing. THE BODY BUILDERS is new classic of the speculative fiction genre, landing like a blow, widening a crack that allows us to perceive the world wholly differently than we ever imagined.
