The Bubble Star by Lesley-Anne Bourne

The characters, setting and atmosphere of The Bubble Star are both rural (northern Ontario) and urban (Toronto). The novel focuses primarily on women -- three sisters -- and their relationships with each other and with men. We have marriage, we have affairs, we have a bit of sex, including a scene in an upscale bamboo furniture boutique. One of the secondary characters is a gay male. A lesbian couple appears, and one of the women is married to a professor who is having an affair with one of the sisters working in retail.
