Zach at Risk by Pamela Shepherd

There really are all sorts of families. Thirteen-year-old Zach knows this because his own family breaks all the rules. A biracial teenager enduring the tribulations of his own adolescence, Zach lives in Seattle with his mom, her lesbian partner, and their gay neighbour, Josiah - not exactly Ozzie and Harriet. On top of that, his new best friend is a young runaway who hustles men on the street for a living, and Zach's after-school job is turning into a nightmare of shame and molestation. This insightful and craftily written novel will take you on the rickety carnival ride that is Zach's young life and add a new dimension to the way you think of 'family.'
