Books Three Through Eight
This universe was always meant to hold eight stories. You are simply early.
Every good story is carried by something larger than itself. Here, it is the tide.
Deep beneath the Island Moon, two sisters: Maharaya and Mahinaʻala are called to discover the gifts the sea has placed inside them. One is bold and bright, first to reach for the unknown. The other listens to the cove's hidden song and understands what others cannot yet hear. Together, they are unstoppable. Apart, they must find their way back to each other.
Rooted in the island heritage of Hawaii and the Philippines, this is a story about courage, identity, and the kind of love that lives between sisters, the love that holds even when the tide turns.
Perfect for bedtime reading, ages 4–10. Also beloved by parents who remember what wonder feels like.
island Roots
Every story here is woven from Filipino and Hawaiian heritage, held with reverence rather than borrowed for decoration. Your child does not have to translate who they are to feel at home in this world.
The Power of Sisterhood
Maharaya and Mahina'ala are not opposites competing for the same crown. One is bold. One listens closely. Both are exactly enough, and so is your child, whichever sister they feel like today.
Seen, Held, and Celebrated
This is not a world that asks a child to perform calm they do not feel. It asks only that they arrive as they are, and stay long enough to feel a little lighter before they go.
The Author's Porch
Marilou Urbi grew up between the coral reefs of the Philippines and the volcanic shores of Hawaii, where she learned that the ocean carries stories the land has forgotten. She writes for every child who has ever felt like a creature of two worlds magical in both.The Island Moon Universe is her offering to the next generation: a place where tenderness is strength, where heritage is honored, and where every reader is invited to feel held, seen, and connected to something much bigger than themselves.
Every world begins somewhere true. This one began between two homelands, in the hands of a woman who grew up carrying both. Come sit a while and hear how it started.
