Here Today by Ann M. Martin (2004)

In 1963, as her restless/irresponsible mother gradually abandons the family, eleven-year-old Ellie takes charge of her younger siblings, while also trying to deal with acts of prejudice toward the "misfits" that live on her street. The dissolution of her family is gradual and Martin does an impressive job of portraying the pre-adolescent daughter's awakening and realization of her mother's weaknesses. Loving and hating in equal and understandable portions. Hard in many ways to read - yet promising in the knowledge that those who care, care deeply and will rise to the occasion and get you through. Ages: 11+
