A new installment in the English/Spanish bilingual “Teeny Tiendas” board book series spotlights Mrs. Sierra’s hardware store. The store sells a host of tools, from hammers and mallets to screws and pliers. A diverse cast of neighborhood customers of all ages find just what they need, often with the help of the competent, purple-haired Mrs. Sierra. The final pages show everyone gathered at the school playground, putting their purchases to use as they collectively make repairs and spruce up the play equipment.
