Set on a fictional island similar to Polynesia, this novel gives the reader a realistic view of such contemporary environmental concerns as global warming and economic decline, which result in immigration, exile, and in some cases, solidarity. When a storm floods their island, Nani’s family leaves for the continent. His grandfather, Enoha, decides to stay behind. Before Nani leaves, Enoha entrusts him with letters that tell his story. A long journey begins for Nanin, during which he meets Semeio, another a little boy on his own, and their fates become forever entwined.
