Atlantic signs debut from 'global sleep phenomenon' Stephanie Romiszewski

Atlantic Books has signed the debut book from "global sleep phenomenon" Stephanie Romiszewski.

Drummond Moir, managing director of Atlantic Books, bought rights to Think Less, Sleep More: From Panic and Perfectionism to Stress-Free Sleep directly from the author. The book will be published by Allen & Unwin UK, Atlantic’s solutions-based non-fiction imprint, in January 2026.

Through Alice Latham, Atlantic’s rights director, foreign rights have been bought by seven international publishers: Piper Verlag in Germany, Planeta in Spain, Companhia das Letras in Brazil, Antonio Vallardi Editore in Italy, PWN in Poland, Publica in Romania and CITE Publishing in China, plus US rights to St Martin’s Press, in a deal brokered by George Lucas at Inkwell. 

Romiszewski is a UK-based sleep expert who uses her academic expertise – including degrees in psychology and behavioural sleep medicine and experience within the NHS and Harvard Medical School, including on studies funded by NASA – with "deep and broad" media experience to help people sleep better.

Romiszewski’s 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".

The book also debunks several myths and offers a wealth of counter-intuitive insights.

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."

Moir said: "With eight international publishers secured six months before we’ve even published, this is the book that is going to help the world sleep better. At Atlantic, 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."
