The Bean Trees by Barbara Kingsolver (Greer Family #1)

Clear-eyed and spirited, Taylor Greer grew up poor in rural Kentucky with the goals of avoiding pregnancy and getting away. But when she heads west with high hopes and a barely functional car, she meets the human condition head-on. By the time Taylor arrives in Tucson, Arizona, she has acquired a completely unexpected child, a three-year-old American Indian girl named Turtle, and must somehow come to terms with both motherhood and the necessity for putting down roots. Hers is a story about love and friendship, abandonment and belonging, and the discovery of surprising resources in apparently empty places. Paperback, 1992 Goodreads: 4.01
