After a storm, marine biology student Leo rescues a wounded silver-tailed merman and hides him in his tiny apartment. Beautiful, dangerous, and obsessively devoted, Caspian soon reveals the truth: he is Triton Seven, an escaped genetic experiment from AquaGen’s deep-sea facility. As the corporation hunts him with mercenaries, sonar weapons, and cloning technology, Leo refuses to abandon the “monster” everyone fears. Their bond becomes Caspian’s anchor, pulling him back from madness again and again. Together, they expose AquaGen’s crimes, free the failed experiments, destroy the cloning system, and return to a quiet coastal life—where Caspian finally proposes to the human who saved him from the abyss.
