In a world where love collides with extinction, Invasion of the Mermaids emerges as a haunting story of war, survival, and the brutal cost of choosing one world over another.

As coastal cities begin to vanish beneath violent tides and unexplainable attacks, marine biologist Elena Ward uncovers a terrifying truth—the creatures rising from the deep are not monsters, but an ancient civilization driven to war by human destruction of their oceans. Torn between her growing empathy for the sea-born invaders and her loyalty to the people she swore to protect, Elena becomes trapped between two futures that cannot coexist. Love, science, and duty collide as destiny drags her toward a choice that could end a species… or save it.

The world feels drowned in tension and beauty. Flooded streets glow under broken neon signs, naval fleets drift like steel graves on restless water, and bioluminescent shadows spiral beneath the waves like living constellations.

From shattered research vessels to the glowing cathedrals of the deep, Elena follows the haunting songs echoing through her sonar—voices filled with grief, rage, and ancient memory. Among the merfolk, she meets a silent warrior whose eyes carry centuries of loss, and for the first time, the enemy begins to feel painfully human. Yet as missiles lock onto the horizon and the ocean prepares its final answer, Elena realizes the most dangerous battlefield is not the sea…

it is her heart.
