'Is it possible, asks the text, for a person to be born in the wrong body, at the wrong time? Yes, is the answer. But sometimes, from that agony, a great soul can wrestle something as beautiful and true as this remarkable play.'

'Sarah Kane's last play, written before she killed herself 10 years ago, has been described as a theatrical suicide note. That sells it short. It is so much more: a manifesto for living by one about to die.'

Lyn Gardner, Guardian, 25.7.09

'an extraordinary exploration of the human condition, and of psychological disintegration in particular. It exposes the terrifying clarity of the acute depressive's unblinking certainty that their existence is intolerable and can never be otherwise; the play's title refers to Kane's early morning moments of such cruel lucidity.'

Sam Marlowe, The Times, 28.7.09

'Kane's fractured poetry, lacerating in its anguish and devil-driven dark humour'

Sam Marlowe, The Times, 28.7.09
