Sign in to write a reviewThe book's climax revolves around the real-life 1883 eruption of Krakatoa. The event is treated as a grand spectacle of nature's power rather than a human tragedy. The destruction is immense, but the narrative focuses entirely on the main characters' clever and successful escape. There are no deaths or serious injuries, and the approach is secular and focused on scientific ingenuity. The resolution is entirely hopeful.
This book is perfect for an 8-12 year old who loves to build, tinker, and understand how things work. They appreciate detailed world-building and stories that celebrate intellect and ingenuity over physical conflict. A great fit for a child who enjoys classic adventure tales like those of Jules Verne or who is fascinated by science and history.
The book can be read cold. The language is somewhat formal and of its time (published 1947), which may require explaining a few words. A parent could enhance the experience by looking up the historical eruption of Krakatoa with their child after finishing, to compare the fictional account with the real event. The parent sees their child drawing detailed blueprints for fantastical machines, building complex LEGO creations, or asking endless questions about inventors and historical events. The child is looking for a story that feels both smart and adventurous.
A younger reader (8-9) will be thrilled by the surface-level adventure: the cool inventions, the idea of living on a secret island with unlimited wealth, and the exciting escape from the volcano. An older reader (10-12) will better appreciate the satire of the "Gourmet Government," the cleverness of the scientific explanations, and the overarching theme of creating one's own ideal life, separate from the rest of the world.
Unlike many adventure stories, the conflict is not with a villain but with the forces of nature. The book's unique quality is its singular focus on celebrating human ingenuity, cooperation, and scientific curiosity in a whimsical, pre-steampunk style. It reads like a delightful thought experiment brought to life with meticulous, charming detail.
Professor William Waterman Sherman, a retired teacher, is discovered in the Atlantic Ocean amidst the wreckage of twenty balloons. He then recounts his adventure: his own balloon was damaged, leading him to crash on the island of Krakatoa. There, he found a utopian society of twenty families living in technologically advanced homes, their society funded by a secret diamond mine. He lives with them until the volcano erupts, forcing all the inhabitants to make a daring escape on a platform lifted by their twenty balloons.
