Twelve light-years from Earth lies Thalassa,
an uncharted ocean planet shrouded in storms, secrets,
and the echoes of a vanished past

For Sage Thompson, a fallen big-wave champion haunted by loss and exile, the journey to Thalassa is a last shot at redemption. Once celebrated across the virtual surf world, she now rides the edge of obscurity. But this mission isn’t just about reclaiming a title—it’s personal. Her father vanished on Thalassa years ago during a doomed expedition. Now, Sage follows his path through space in search of answers.

What she finds is beyond imagining: a water-covered world teeming with alien beauty, spiritual resonance, and ethereal songs that speak directly to her soul. As rivalries ignite and ancient forces stir beneath the waves, Sage must confront the truth about her past, her culture, and the fragile line between science and spirit.

Part ecological parable, part cosmic adventure, Songs of Thalassa is a powerful tale of ancestry, awakening, and the mysterious intelligence of the sea.

>>> Excerpts from the book <<<

From Chapter 30, Songs of Thalassa

From Chapter 22, Black Rain

Days ago, the eastern clouds merged with the western storm to form a giant dark mass of angry thunderheads as the wind howled through the valleys and along the cliffs. As the sky let loose its watery burden, the feeble streams grew into raging torrents. It was as if all of Thalassa’s great oceans had evaporated into the sky and were suddenly rushing back to the sea. The storm came in great thundering sheets of water pierced by lightning. Then it would die down for a few minutes or an hour, just enough for them to see the mainland across the bay through the mists, but then it would start up again.

A spider web of rivulets, streams, and rivers pouring off the island filled with so much yellow-red-black sediment that the sea had become a swirling cauldron of brown-and-white madness. The tides had grown frighteningly large, seemingly overnight. The inland sea drained at night then rushed back at dawn as a huge, frothing chocolate wall. In front of the cave, the sea came in from both sides, colliding in a gigantic upheaval of foam that shook the island in its rage. And it was growing; every day the tides were bigger, with the high tide approaching the edge of their cave. Although she had hope that it would completely drain the inland sea and they could scramble across, she worried about seeing her way through the veiled madness.”

  • The Fermi Paradox

    The Fermi Paradox is a great way to think about the possibility of life, in this case technologically advanced civilizations in the universe. Below is the text from an early draft of SOT that was deleted from the book. This is a conversation the crew had in space on the way to Thalassa and is…

  • Mythology & Beliefs

    A large part of SOT involves Sage’s cultural upbringing and her embracing of Hawaiian culture, and eventually a new worldview. Here I explore aspects of Hawaiian mythology and culture including in the book in more detail. I also explore the concept of Pantheism. “Hanau ka poThe night gave birth Hanau Kumulipo i ka po, he…

  • Music of Thalassa

    Earth is teeming with life, all literally bursting with sound. On land we hear these sounds every day and most people are familiar with the noises of the forest: the hooting, chirping, moaning, howling, tweeting, clucking, whistling, squawking and hooting that creates a complex sonic melody. The sound of nature is everywhere but we don’t…

  • Sage: Heroine’s Journey

    Sage’s story, like many in modern fiction, was modeled after Joseph Campbell’s The Hero’s Journey but adapted for a woman to the Heroine’s journey.

  • Geology of Thalassa

    The geology of Thalassa was created based on real-world examples of planetary dynamics on Earth and other planets, especially Mars. Here I present the research concepts I used to create the geology, geography, and oceanography of the planet. To begin, let’s travel back in time about 100 million years ago to the planet Thalassa… At…

  • Waves of Thalassa

    So, you might ask, can we really surf on a planet like Thalassa? What does the science say? Believe it or not, this question has been studied and the answer is yes!. But as a surfer a better question is what kind of waves would we find? In SOT I based the waves at the…

  • Life on Thalassa

    Although we have discovered thousands of exoplanets in the last decade we know of only one planet with life: Earth. So, as a marine biologist I based life on Thalassa using the scientific foundations and evolutionary history of what we know about primitive life on Earth, with some added twists of course. Since we don’t…

  • Origins of Thalassa’s Cetaceans

    As a marine biologist I am always spellbound watching whales on the open sea. Witnessing their majestic movements, they are the most marine of all creatures, but I never fully appreciated their origins until I researched the topic before writing SOT. I focused on the ancestors of cetaceans because they are super-cool and are a…
