Fiona, a New York librarian filled with a sense of adventure and a desire to do good, heads to Kenya to run the camel bookmobile. She has long romanticized Africa, and she arrives determined but naive. Her most remote stop is Mididima, a seminomadic farming village with a makeshift school, led by Matani, who has studied in Nairobi but returned to educate his fellow villagers. Young Kanika, who wants to leave and study as well; the reclusive Scar Boy; and their families are among Fiona's patrons. When Scar Boy doesn't return the books he's borrowed, the overly rigid local librarian threatens to end the Mididima stop. Fiona, Matani, and Kanika each have stake in keeping the bookmobile coming, so they all try to get the boy to return them. However, he has his own compelling reason to keep them. All of the characters take a turn at narrating chapters, allowing readers to understand their place in the story more fully. Ultimately, each one is changed by the bookmobile, but not in ways that they (or we) might expect. Teens can enjoy not only the multicultural aspect of this novel but also the quiet drama and plot twists that impart the differences and similarities among the characters.
