Martín Anderson, author of ‘My Neighbor Mr. Lerner,’ takes us into the world of Sonia Concepción. Sonia is a fiercely independent single mother of two, who still believes in the tradition and values with which she was raised in Puerto Rico. She works hard to raise her son Miguel Angel and daughter Marisol. And she will do anything to defend them from the sometimes harsh realities of living in the Puerto Rican Diaspora of Chicago in the late 70s, even if this means sacrificing her life or taking the life of one who presents a danger to her children.
