'When we spoke, I never knew what Olive would reveal to me. There were nights where she would lie next to me and pour herself out into the darkness, and others where it seemed she was hardly there at all.'

Millie is in her final year at a Catholic girls' school, subdued by the conformity of her life and her parents' quiet pain. But when her schoolmate Olive moves in next door, it marks the beginning of an intoxicating friendship that changes everything. In all the ways Millie feels unsure and half-formed, Olive, an aspiring actor from a devoutly Catholic family, seems at ease with her place in the world.

On the precipice of freedom, the two young women seize nights out and a school retreat as opportunities to further their own increasingly uncertain ends. Olive urges Millie on in her sexual encounters, but Millie is only becoming more consumed by Olive. When they're not staying up all night talking, they're watching each other from their bedroom windows - their selves are becoming blurred, their lives intimately mirrored.

That makes it all the more excruciating when, seemingly out of nowhere, Olive cuts off all contact. For all her efforts, Millie cannot understand what's changed between them. Has she missed something? Or was their friendship, for Olive, just another performance?

An emotionally charged novel of expectation, compulsion and desire, Lead Us Not charts the unseen currents of tension and control that shape a friendship.
