With her characteristic deftness and sensitivity, Newbery medalist Linda Sue Park recreates the plight of migratory Sudanese children who face the trials of a harsh environment, scarce resources and limited opportunity, and lives marked with social and political turmoil. This novel weaves together the stories of Nya, a girl whose life is transformed by the creation of a freshwater well in her village, and the true-life saga of Salva, one of the “lost boys” of Sudan, and his years-journey from Sudan to Ethiopia and Kenya to Rochester, New York and back. This story will give readers an insight into a world unknown to many, and can inspire social activism.
