Since, 1990, Louise Glück has been exploring a form that is, according to poet Robert Hass, her invention. Vita Nova -- like its immediate predecessors, a book-length sequence -- combines the ecstatic utterance of The Wild Iris with the worldly dramas elaborated in Meadowlands. Vita Nova is a book that exists in the long moment of spring, a book of deaths and beginnings, resignation and hope, brutal, luminous, and farseeing. Like late Yeats, Vita Nova dares large statement. By turns stern interlocutor and ardent novitiate, Glück compasses the essential human paradox, a terrifying act of perspective that brings into resolution the smallest human hope and the vast forces that shape and thwart it.
