With her new memoir Insomnia, Marina Benjamin has produced an unsettling account of an unsettling condition that treats our inability to sleep not as a disorder, but as an existential experience that can electrify our understanding of ourselves, and of creativity and love.

Insomnia is a bravura piece of writing. At once philosophical and poetical, the book ranges widely over history and culture, literature and art, exploring a threshold experience that is intimately involved with trespass and contamination: the illicit importing of day into night. With Insomnia, Benjamin aims to light up the workings of our inner minds, delivering a startlingly fresh look at what it means to be wakeful in the dark.
