Atlantic Books signs ‘global sleep phenomenon’ Stephanie Romiszewski

14th March 2025

Atlantic Books has signed Think Less, Sleep More, the debut non-fiction book by Stephanie Romiszewski, and has accepted several pre-emptive bids from publishers around the world on the eve of the London Book Fair.

Think Less, Sleep More: From Panic and Perfectionism to Stress-Free Sleep will be published by Allen & Unwin UK, Atlantic’s solutions-based non-fiction imprint, in Spring 2026. Through Alice Latham, Atlantic’s Rights Director, German rights were pre-empted by Martin Janik at Piper; Romanian rights by Publica, Spanish rights by Rocio Carmona at Planeta; and US rights by Elizabeth Beier at St Martin’s Press, in a deal brokered by George Lucas at Inkwell. Drummond Moir, Managing Director of Atlantic Books, bought rights directly from the author.

Stephanie Romiszewski has helped over 10, 000 patients sleep better. A clear-eyed and passionate antidote to both individual sleep anxiety and our current obsessive, perfectionist culture, her first book will unpack the science and fundamentals of sleep – including misunderstood concepts such as sleep drive, sleep debt and sleep sensitivity – and arm readers with simple tools for how we can each improve something we spend a third of our lives doing. Stephanie will debunk several myths and offer a wealth of counterintuitive insights, including why your morning routine is far more important than your bedtime routine; how to trust your body’s natural sleep drive and rhythms; why ‘bad’ nights don’t ruin your health; and why sleep isn’t as fragile as we think: it’s adaptable, resilient, and smarter than any hack you could throw at it.

Stephanie Romiszewski said,

‘I don’t stress about sleep—ever. And that’s not because I’m special or immune to bad nights. I’ve just learned that the more you try to control sleep, the worse it gets. Sleep isn’t the enemy—it’s your best friend. And when you stop blaming it and start working with it, sleeping well becomes so much simpler than we’ve been led to believe. No hacks, no over thinking!’

Drummond Moir said,

‘We couldn’t be more thrilled to be working with Stephanie. As someone who has always been a terrible sleeper, I’m excited to know that her deep expertise, reassuring voice and liberating philosophy will help readers around the globe transform a third of their lives.’
