In the winter of 2020, Annabel Abbs experienced a series of bereavements. As she grieved, she kept busy by day, but at night sleep eluded her. And yet her sleeplessness led to a profound and unexpected discovery: her Night Self. As the night transformed into a place of creativity and liberation, Annabel found she wasn't alone. Drawing on the latest science, which shows we are more imaginative, open-minded and reflective at night, Annabel set out to discover the potential of her Night Self. 'Sleepless' follows her journey, from midnight hikes to starlit swims, from Singapore, the brightest city on Earth, to the darkest corner of the Arctic Circle, and finally to that most elusive of places - sleep.
