Sweet Ruin by Cathi Hanauer

No one knows better than Elayna Leopold that life can change in an instant. On the surface she appears typical of any other young married woman who spent her twenties chasing dreams in the city and ended up spending her thirties chasing children in the suburbs. But spring marks Elayna's emergence after two years of grieving the loss of her second child - and the reawakening of feelings she thought she had lost forever.
   When a handsome young artist helps Elayna rediscover her passion for life, she finds herself on the brink of risking everything she cares for by succumbing to the almost unbearable temptation of a younger man who is not only physically irresistible, but hopelessly in love with her.
   Tender, provocative, startingly real and impossible to put down, Sweet Ruin is a story every woman should read at least once.
