The setting is rural Kentucky in 1936. Cussy (aka Bluet) has a rare genetic condition that produces blue skin (met-hemoglobinemia). Without marriage prospects (by choice), Cussy joins the Pack Horse Library Project, delivering books to remote desperately poor hill communities. The transformative power of books and literacy is offset by shocking prejudice against “coloreds” and some crushing poverty. So be warned, readers will shed some tears. Thanks Joyce, for this recommendation.
