Tress of the Emerald Sea is a wonderful, layered adventure that evolves as the priorities of Tress, our main character, ebb and shift. Tress is a young girl from a barely habitable rock, surrounded by a sea of spores that turn into vines when they touch water. Her friend and love interest, Charlie, the son of the island’s Duke, is sent to the island of the King to be married. When he makes himself completely undesirable, the King sends him to the Midnight Sea (another of several spore seas, each with their own distinct properties) where he is captured by the fearsome Sorceress.
Tress, when she finds out, sets off on a grand adventure to save him. On the way, she becomes part of a pirate crew, driven by the fearsome Captain Crow, and meets Fort, Ann, and Salay, as well as Hoid, a world-hopping character of the wider Cosmere who is cursed by the Sorceress. As Tress seeks Charlie, she becomes embroiled in a conflict between the crew and their captain. This multi-tiered adventure keeps the story fresh and engaging. Of the people Tress meets, Ulaam in particular stands out as a delightful character whose presence brings fun and unpredictability to his scenes. An ear on your arm, anyone?
One of the key strengths of the novel is how its conflicts are solved through different means. Some through combat, sure, but also through wit and quick-thinking. These keep the tension high in the right places, and show Sanderson’s skill in crafting a variety of situations and solutions for his characters. I am a massive fan of different ways of solving problems beyond force—the scene with Xixis the dragon was my favourite—so this scratched a real itch for me.
The world building, as one would expect of Sanderson, is top-tier. The spores and how they function are cool and varied, and the way they are built into the story is very satisfying. Likewise, the narrative voice, provided by the cursed Hoid (who is rendered to something of a ‘village idiot’ with no fashion sense), connects the novel to the broader Cosmere. Hoid is witty and fun, and this keeps the narrative light. It is also refreshing to have the story told by a third party who is able to comment personally on what is happening without being the centre of the story. I did find some of Hoid’s observations to disrupt the immersion in places—e.g., the reference to ‘laptops’ being a key one. I get that this is supposed to broaden out the links to the world beyond, but, as someone unfamiliar with the rest of the universe, I found it a little jarring.
Also, Tress’s character development, while clearly central to the story, does sometimes suffer from exposition that I found a little heavy-handed. There are moments when the narrative explicitly states that Tress is changing or growing, even when I think readers can see these changes organically. It’s a little unnecessary and on-the-nose. And, lastly—SPOILERS—certain plot elements create minor inconsistencies that detract from the otherwise cohesive world. For example, the Sorceress has inhabited the planet for years and possesses advanced knowledge of technology that Tress is only beginning to develop. When Tress offers to trade this technology, the Sorceress dismisses it—yet later, her guards are defeated by this very same technology. This inconsistency feels like an oversight that somewhat weakens the internal logic of the story.
Regardless of some minor flaws, Tress of the Emerald Sea is an easygoing, refreshing sci-fi/fantasy adventure with a cast of loveable characters. The story is accessible and easy to follow, is told with humour, and sits against a well-fleshed-out and intriguing world. It gets a big ‘recommend’ from me!
