The Princess of Insomnia is a wonderful adventure, a fantasy novel, a satire, a psychoanalysis, an ode to difference and uprightness, a love story, a somnambulist fairy tale – as the German author of many faces and cosmic dimensions, Walter Moers, calls it – and much more. Moers's unique writing transcends the boundaries of reality and dream. It is precisely the multifacetedness with which he repeatedly surprises and delights that gives his works the original stamp of a supreme masterpiece.

Princess Dilia, the least bored aristocrat in all of Zamonia, suffers from incurable insomnia and in her sleepless hours she invents all sorts of things, but she prefers to play with words. On one of her sleepless nights, she is visited by a personified nightmare in the form of the evil and mysterious Havarius Opal, who wants to drive her mad. They embark on a journey through Dilia's brain, where they meet bizarre imaginary creatures, many good, but even more evil and bloodthirsty, in whom colored blood flows, and between them, similar to our real world, there is an eternal and cruel struggle for survival in the sense of: Who will be whom? and Who is the predator and who is the prey? Moers surprises with unexpected twists, because the evil nature of Havarius Opal gradually softens during their miraculous story and a kind of love bond is formed between them. Some Moersel scholars compare Dilia to Sleeping Beauty, and Havarius Opal to a prince (from a dream). (taken from the general page emka.si)
