Full Summary

The novel opens with Skipper, the youngest sister, tending to her mussel rope at Gull Gang Rock, only to find it stripped clean. The theft, combined with the recent disappearance of her eldest sister Nora, pushes her to act. Nora, who worked for Renewal, a powerful agricultural corporation, vanished over a month ago; her colleague John reported her missing, and her last paycheck bounced. Skipper is convinced Nora wouldn't have abandoned a chipped mug she painted with bees, a keepsake Nora kept for ten years.

At a family dinner, Skipper announces she will sail to the city to find Nora. Carmen, a nurse who recently broke up with her girlfriend Ollie, initially objects but eventually agrees to accompany her. They set off on the Bumblebee, the family sailboat, navigating a world of rising seas, submerged towns, and environmental decay. Along the way, they encounter mutated wildlife, a blight that destroys harvests, and the omnipresent influence of Renewal, which sells its Amaranthine treatment to farmers.

In the city, they find Nora's apartment ransacked and learn from a lab technician, Marcus, that Nora had been searching for a blight-resistant soybean. Marcus gives them a letter from Nora, which leads them to a town farther north. There, they meet Jackson Barker, a charismatic but unstable man who claims Renewal murdered his family. Jackson joins their quest, and they continue north.

After decoding a hidden message in a letter from Nora—using a substitution cipher based on syllable counts—they learn Nora is trapped in Vault City, a Renewal company town in the polar region. They decide to rescue her. The voyage is harrowing: they face storms, a pirate attack on a floating platform, and a near-fatal encounter with a giant garbage patch. Jackson becomes increasingly erratic, hoarding the egg-shaped navigation device they acquired and draining the boat's batteries. When he tries to change course and abandon the mission, he transforms into a bear-like figure, attacks Carmen, and is washed overboard during a jibe.

The sisters continue alone, losing the Bumblebee when it sinks in icy waters near Vault City. They are rescued and brought to the clinic, where they are forced into indentured labor. Carmen works as a nurse, secretly stealing drugs to help a resistance contact, Emilie, who claims to have information about Nora. However, Emilie later admits she lied; Nora is not in the vault. Carmen, desperate, volunteers to enter the vault during a disease outbreak. Inside, she discovers that Nora had already escaped months earlier, with the help of a maintenance engineer. Nora had found the blight-resistant soybean and learned that Renewal was manufacturing the blight. She left behind a package containing syringes of golden liquid—samples of the engineered blight—and a notebook.

Carmen and Skipper escape Vault City during a pirate attack and sail to Sisterland, a warm, green country. There, they find Nora working as a lab assistant under the name Aster Atco. The sisters reunite, and Nora reveals the full truth: Renewal intentionally expanded the blight to profit from its Amaranthine treatment. She had been investigating this conspiracy, which led to her disappearance.

The sisters decide to expose Renewal. Nora, with the help of Professor Rafael Aguirre, sequences the blight samples and prepares to go public. Carmen, who has been carrying the seeds, disappears after leaving for home, but later contacts them, safe. They lure Renewal into a trap, releasing all the vault data during a live interview. The evidence leads to an investigation, and Renewal's assets are seized.

In the aftermath, Carmen returns home and repaints the house with Uncle Tot. Nora begins a doctorate and works with Rafael. Skipper builds a new boat, the Equilateral, and announces she will sail around the world. The novel ends with Skipper sailing away, leaving Nora and Hilda (Nora's adopted daughter) to watch her go.
