The Coral Parliament [EPUB ebook] 
A Symphony of Survival

2147. Earth is a water world. Humanity clings to survival in submerged city-states, haunted by the ghosts of a drowned past. In Aquatica, built on the ruins of Miami, bioluminescent structures pulse with life, a fragile beacon of hope.  But beneath the surface, tensions simmer. Resources are scarce, and the uneasy peace with the militaristic Abyssus threatens to shatter.
Dr. Hannah Jenkins, a marine biologist, journeys into the abyssal depths, seeking solutions in the vibrant coral reefs. Her discovery is paradigm-shifting: a sentient coral parliament, communicating through a symphony of light and color.  This revelation ignites a chain reaction that will redefine the future of the ocean and all who dwell within it.
Meanwhile, Mallory Finch, a linguist haunted by the Great Flood, finds a new purpose: deciphering the coral’s complex language.  She becomes an interspecies ambassador, a bridge between two worlds on the brink of war.  But as she delves deeper, she uncovers a history of ecological exploitation, a narrative of coral grief and resentment.  The reefs demand a voice, a seat at the table in a world they once ruled.
As Aquatica cautiously embraces the possibility of a coral alliance, Abyssus, driven by a fear of losing human dominance, prepares for a devastating preemptive strike.  Beyond the city-states, the nomadic jellyfish clans foresee a cataclysm, their pulsating bioluminescence carrying a cryptic warning.  Cassandra Marquez, a jellyfish whisperer, joins Mallory, her intuitive understanding of the ocean’s rhythms adding a chilling urgency to the unfolding crisis. A seismic event of catastrophic proportions is imminent, threatening to shatter the fragile stability of their underwater world.
Amidst political intrigue and escalating tensions, a saboteur within Aquatica fans the flames of conflict. Mallory, racing against time and the tremors of the ocean floor, must expose the traitor and forge a path towards unity before disaster engulfs them all.  The fate of humanity and the coral rests in her hands, a delicate balance between survival and destruction in a world where the symphony of life hangs by a thread. Will they find harmony or will the ocean’s silence reign supreme?
