Here are some I've liked:
Thursdays at Eight by Debbie Macomber - 4 women in various stages of life become friends in a writing class. They continue their friendship by meeting on Thursday mornings at eight for breakfast and discussing their lives. Quick, light read.
Susannah's Garden by Debbie Macomber - a woman returns to her childhood home to pack things up as her mother is placed in a nursing home. She explores her relationship with her parents, her husband and her children. Quick, light read.
Dear John by Nicholas Sparks - there is a strong component of young love across the miles but also of a man discovering his sense of self and figuring out his relationship with his loving, yet distant father. Easy read.
Suzanne's Diary for Nicholas by James Patterson - "Katie Wilkinson's boyfriend Matt dumps her; not a total cad, he leaves her a gift, a diary kept by Suzanne, his first wife, for their son Nicholas. Though it's not exactly the diamond ring Katie was hoping for, she's unable to make herself destroy the diary--against her better judgment, Katie begins to read." Tear jerker.
Sam's Letters to Jennifer - "Jennifer, a newspaper columnist who's grieving the death of her husband, has more reason to mourn when her beloved grandmother, Sam, falls into a coma. Jennifer rushes to Sam's home in Lake Geneva, Wis., where she finds a packet of letters addressed to her. The letters detail her grandmother's life story, including an affair she had with a mysterious man. Jennifer takes comfort in the letters, and at the same time, embarks on her own romance with Brendan, an old friend." Sweet and sentimental.
Angry Housewives Eating Bon Bons by Lorna Landvik - "Five friends live through three decades of marriages, child raising, neighborhood parties, bad husbands and good brownies...novel of female bonding..." Funny, reminiscent.
