Deux (French Kiss Chronicles #1)
Em Petrova

Jane is a wife and mother who's stuck in a rut. Spending too much time at the gym perfecting her physique, she learns that what she really wants is someone new to share her body with.
After Margot's divorce, she's feeling frumpy and unloved. Until one day, Jane corners her in the dressing room and makes it perfectly clear that she finds her ripe curves desirable.
Together, the couple shares the passion they thought long dead, and in doing so, discover they harbor a deeper need—to find love.
