Gem, an orphaned firefly adopted by grasshopper parents, wants the only thing in the world that she can’t have. Desperate to fit in, she wants to turn her glow off.  Growing up in a grasshopper village on a tropical island, she’s bullied and teased for her light at school.  Her parents enlist the help of a beloved village elder to help Gem learn to use her light and teach her how to become a bright, strong firefly.

Secretly, she wants to turn off her glow forever. But when her classmates are in grave danger, Gem’s the only one who can save them. She faces the choice of becoming her true self or running away from the only home she’s ever known.
