Lost in the Atlantic Valley is one of Luis Senarens’s many Frank Reade dime novels from the late nineteenth and early twentieth centuries, working in the proto science fiction adventure mode that made him one of the most influential American genre writers of his era. Senarens wrote hundreds of stories about young inventor Frank Reade and his various sons and assistants, often under the pen name Noname, and the cumulative output established many of the conventions that would later define the science fiction genre proper.
The Atlantic valley setting hints at one of the more interesting premises in the wider Frank Reade catalogue. The deep ocean trenches and ridges of the Atlantic floor were known to nineteenth century geography but not yet explored in any meaningful detail, and the lost in the Atlantic valley framing gives Senarens room to send his protagonists into territory that real science of the period could only speculate about. The Frank Reade submarine vessels that recur across the series provide the means of investigation, and the deep ocean settings allow for the kind of strange creatures, lost civilizations, and mysterious phenomena that the dime novel genre rewarded.
The Frank Reade stories typically follow a young American inventor and his crew of friends and engineers as they build a remarkable new machine and use it to explore some remote and dangerous corner of the world. The stories combined adventure plotting with an interest in plausible engineering speculation, which made them important precursors to the science fiction that would emerge as a distinct genre in the early twentieth century. Senarens corresponded for years with Jules Verne, who admired the American writer’s work, and the influence on later writers including the early pulp science fiction authors of the 1920s and 1930s was substantial.
The prose is brisk, the action moves, and the period assumptions about race, empire, and the American frontier are very much present in ways modern readers will need to navigate. For scholars of early American popular literature, of the prehistory of science fiction, or of the dime novel as a publishing phenomenon, Senarens’s work is essential. For general readers, his stories are now historical curiosities more than living literature, but they retain real interest as artifacts of a particular moment in American imaginative life.
