It is summer, and Sebastian is in treatment following a breakdown that has left him with a fragile hold on reality and a persistent hunger to connect with the mother who abandoned him as a child.

His therapist, Martin, is also facing challenges, including his adopted daughter Olivia's tenuous relationship with her biological mother - a predicament that makes Sebastian's struggle feel uncannily close to her own. Olivia is producing a radio series on natural disasters, which itself seems to be running parallel to the events unfolding in her personal life, as her best friend Lucy faces a grave diagnosis and her husband, Francis, pursues his mission of rewilding the world.

Over the course of the next year their fates collide in outrageous and poignant ways, as each of their destinies is revealed in a marvellous new light.

Written with Edward St Aubyn's trademark wit and inimitable style, Parallel Lines is a novel about connection, love and the cascading consequences of our choices. It is a vibrant, moving celebration of the life of the spirit and the life of the mind from one of our most irresistible storytellers.
