Katie can't stand to look at another plain old potato, so she wishes them away. And soon after, a rot begins to spread across the fields of Ireland. As the potato crops wither and more and more people get sick, Katie believes she's at fault. Even when Grand Da agrees that she and her cousin should join her father in Boston, Katie still feels guilty about having wished the potatoes away. Inspired by her own heritage, Barbara Shook Hazen has spun this poignant tale of the Irish potato famine. Caldecott Medal winner Emily Arnold McCully brings it to life in graceful, tender watercolors.
