From the internationally acclaimed author of Purge, comes a deliciously dark drama that is a searing portrait of the exploitation of women's bodies and the extremes to which people will go for beauty. After the suicide of her mother, Norma is left alone with their secret - her hair reacts to changes in mood, moving of its own accord - but quickly realises a sinister truth lies beneath her life. A spellbinding new novel set in present-day Helsinki.
