Hunger, by Donna Jo Napoli

Life in the Irish countryside has alwatys been a bit precarious.  Lorraine and her family lease land from an English lord and subsist on the potatoes they grow, selling their grain harvest for income.  But when the crop fails in 1846, things start to look dire.  And in the year that follows, mass starvation leads to societal collapse.  

In the midst of the suffering, Lorraine befriends the naive but kind-hearted daughter of their lord named Susanna.  Miss Susannais a complicated character: arrogant, ignorant, and rude, but she nonetheless performs important acts oif charity that ultimately keep Lorraine alive.

Based entirely on historical fact, this is a story that won't exactly qualify as a pleasure read.  So while Napoli writes excellent historical fiction, but it's hard to imagine too many young people who would pick this book to read on the beach.  That's a shame as the book doesn't just serve as a historical account, but raises significant questions about how racism and ignorance affect the topic of immigration and of charity.
