Cindy Haug was born in Hamar, daughter of a Lower Court judge, and was educated at Statens kunst- og håndverksskole (Oslo National Academy of the Arts), worked as a domestic help and carer, is married, and has one child.
Since her debut novel Se deg ikke tilbake mot Europa og bli stein – O, Eurydike, published in 1982, she has turned her back on large-scale story-telling and has mixed different language registers, highbrow and lowbrow, kitsch and artistic, to create a postmodern aesthetic and experience of the world. Her short prose, poetry, children's verses, and radio plays feature both frenzied games with masks and costumes and an insistent sadness that is inevitably orchestrated. Her poetry collection Mitt liv, fiksjoner, 1984, which presents the author as a bride on the front cover and as "Madonna" on the back cover, adopts an ironic posture within the insistent contrivance typical of the 1980s. Her more recent works are the collections Gaupehjerte, 1993, Tiende bok, 1994, and Fjærtegn, 1997.
