Ami lives on Culion, an island for people who have leprosy. Her mother is among the infected. She loves her home - with its blue seas and lush forests, Culion contains all she knows and loves. But the arrival of malicious government official Mr Zamora changes her world forever: islanders untouched by sickness are forced to leave.

Banished across the sea, shes desperate to return before her mother’s death. She finds a strange and fragile hope in a colony of butterflies. Can they lead her home before its too late?
