When your grandmother runs a pizzeria, your life doesn’t look like your peers’ lives. On one hand, she can help with wise advice and support you in a hard moment; on the other, she raises a lot of questions among those around her and even causes misunderstandings with close people. Will it be possible for seven-year-old Stella to keep this special bond with her grandmother and save the family? An unpredictable—but so charming—Naples, a noisy pizzeria where the secrets of the pizzaiolo are revealed one by one, and a harmonious weaving of eternal themes in Diana Martos’s new novel “My Grandmother Is a Pizzeria.”
