Will they flourish? Or will humanity sink into extinction? Mermaid Spring, the second installment of the four-part science fiction fantasy Mermaids series, takes up a century after the apocalyptic Great Dying. The old world has gradually passed away while the population of Orchardton Hall increases exponentially as Dr. Karen continues her experimentation with enhanced birthing techniques and witnesses the origin of a new species. A new danger is arising across the sea in the land once known as America. As the unleashing of nanotechnology rears its ugly head and threatens not only the earth but the entire galaxy, the mermaids, the Ladies of the Lake, must remain vigilant against the insanity creeping into the world. Disruption is inevitable as the good doctor is kidnapped and held prisoner by a mad scientist from her past who hasn't forgotten his love for her. Can the Ladies of the Lake effect a rescue, or will they succumb to the lure of forgetfulness and sleep?
