A story about making new friends and missing home, wherever home may be. Mónica and Hannah are school kids in the big city. Together, they have formed the Homesick Club, since they are both from far away. Mónica misses the family of hummingbirds that she and her grandmother would feed in her backyard in Bolivia every day. Hannah misses the sunshine and the tiny tortoise that lived near her house in Israel. When a new teacher, Miss Shelby, arrives from Texas, the girls discover that she misses her home, too, especially the huge sky full of stars and a Southern treat known as Hummingbird Cake. The girls ask Miss Shelby to join their club, then Mónica decides she will bring a surprise for show and tell — a surprise that brings Miss Shelby close to tears.
