An ABC introduction to a little girl's neighborhood in all its rich detail.M is for las muralistas, making murals of island vistas. Waterfalls that hide brick walls. Rainforest full of tropical trees.N is for the noisy neighbors who sit on the stoop and catch the breeze.When Ava's friend Chien visits her in the Barrio, she takes him on a tour of all of her favorite things about the neighborhood. From fire hydrants to ice cream trucks, bodegas to vacant lots, the sights and sounds of the Barrio -- even the less perfect things -- come to life in the poetic words of Quiara Hudes, author of the Tony Award-winning musical IN THE HEIGHTS.
