Grandpa and Luka share the same birthday and today they get to celebrate it with the whole 'aiga. Grandpa is also a storyteller and surprises his grandchildren with a Samoan Siapo that tells a very special story about Samoa's journey to independence. Grandpa's Siapo is the only picture story book in the world that introduces readers to historical events in Samoa and key Samoan figures who helped Samoa to become the first Pacific island nation to gain independence in 1962. This story develops cultural understandings and knowledge around colonisation as well as New Zealand's historical ties with Samoa in a safe and accessible way. The book also received the blessing from Fialaui‘afualeafi Tamasese – daughter of Samoa’s first Co-Head of State, Tupua Tamasese Mea‘ole, and the oldest grandchild of Ta‘isi Olaf Frederick Nelson.
