After a childhood marked by pain, Rena Greenblatt has found the strength to build a successful career as a photographer. Like the ultrasensitive infrared film she uses, Rena sees what others don't see, and finds a form of love. By photographing men's bodies, she hopes to glimpse their souls. Away from her lover, Aziz, stuck in Florence with her infuriating stepmother and her ageing, unwell father, Rena confronts not only the masterpieces of the Renaissance but the banal inconveniences of a family holiday. At the same time, she finds herself travelling into dark and passionate memories that will lead her to a series of disturbing revelations. With exceptional flair and talent, Nancy Huston explores the links between family intimacies and our collective lives, between destruction and creation. In the spirit of her bestselling novel Fault Lines, Infrared is a story about how childhood, family, and our culture all have a direct impact on our sexuality.
