Award-winning journalist Jo Marchant returns with a mind-bending exploration of the shifting science behind how we understand time

What if the present moment – the ‘now’ we all inhabit – isn’t just a tick of the clock?

We feel that the present is everything; all we can know. Yet physics finds no universal ’now’. To explore what a moment really is, In Search of Now draws on state-of-the-art discoveries in neuroscience, psychology, cosmology and quantum physics, revealing a dynamic, creative process in which we all play a part.

Jo Marchant shows how we each carve out our lived experience – sensations and emotions, actions and decisions – through our interactions with the world. Far from being an illusion or a mere slice of time, she argues that this evolving, interconnected tapestry is the source of our lives and selves, and perhaps even reality itself.

Join Jo to explore the secrets of how our lives really unfold – and rediscover the creative power of ‘now’.


“A superb, illuminating book that will change the way you think about the present moment”

Anil K. Seth

“In this profound and brilliant treatise on the nature of reality, Marchant asks the greatest question: what does it mean to exist? The answer brings a dazzling exploration of science and philosophy, from consciousness to quarks, illuminating our embodied experience within the grandeur of an unfolding unfeeling Universe. A phenomenal, wonderful, ambitious work that won’t just shift your perspective but rather catapult it into another dimension”

Kevin Fong

“In clear and engaging prose, Jo Marchant guides us through the maze that intertwines our notions of time, causality, identity, and reality - and points us in the direction of a new reframing. In Search of Now is a splendid example of the best sort of synthetic thinking and writing”
