First Fall by Genevieve Fortin

Audrey Eriksson gladly gave up the fast-paced city living and all its complications years ago. Living in quiet St. Georges suits her perfectly and she's quite content with her surroundings. But then an unexpected work assignment throws her off-kilter professionally, and a growing attraction to her neighbor threatens to upend her personal life as well.

New to the neighborhood and absorbed in her own problems with a failing marriage, Marielle Demers welcomes her easy friendship with Audrey. Soon the nature of their friendship forces her to question her feelings and when she sees Audrey with another woman she realizes that she'd prefer to be the one who's dating Audrey. She keeps the revelation secret as long as she can, but her feelings prove harder and harder to ignore.

Can two women who prefer an uncomplicated life handle the messiness of falling in love?
