A Wish in the Dark by Christina Soontornvat

A boy on the run. A girl determined to find him. A compelling fantasy looks at issues of privilege, protest, and justice. All light in chattana is created by one man — The Governor, who appeared after the great fire to bring peace and order to the city. For Pong, who was born in namwon prison, the magical lights represent freedom, and he dreams of the day he will be able to walk among them.
