Hyperdream is a major new novel by celebrated French author Hélène Cixous. It is a literary tour de force, returning anew to challenge necessity itself, the most implacable of human certainties: you die in the end - and that's the end. For you, for me.

But what if? What if death did not inevitably spell the end of life?

Hyperdream invests this fragile, tentative suspension of disbelief with the sheer force of its poetic audacity, inventing a sort of magic telephone: a wireless lifeline against all the odds to the dearly departed.

It is a book about time, age, love and the greatest loss. A book which turns on death: on the question or the moment of death, depending on it, expecting it, living off it, taking place at once before and after, but at the same time turning against it, contesting it, outwriting it hopefully, desperately, performatively, as an interruptible interruption.

Hyperdream is a book of mourning, but also of morning, a tragedy-with-comedy and a universal family romance in which it transpires that the narrator is the veritable offspring of a "treasure of literature" in the form of a bed, purchased by her mother from a certain W. Benjamin in 1934, slept on for 40 years by her brother and dreamt of by her friend "J.D."
