Ikal is a student at Muhammadiyah Elementary, on the Indonesian island of Belitong, where graduating from sixth grade is considered a major achievement. His school is under constant threat of closure. In fact, Ikal and his friends - a group called The Rainbow Troops - face threats from every angle: pessimistic, corrupt government officials; greedy corporations hardly distinguishable from the colonialism they've replaced; deepening poverty and crumbling infrastructure; and their own faltering self-confidence. But in the form of two extraordinary teachers, they also have hope, and Ikal's education is an uplifting one, in and out of the classroom.

You will cheer for Ikal and his friends as they defy the town's powerful tin miners. Meet his first love - a hand with half-moon fingernails that passes him the chalk his teacher sent him to buy. You will roar in support of Lintang, the class's barefoot maths genius, as he bests the rich company children in an academic challenge.
