The Seraphim Tide. The Buried Angels Saga

A dangerous billionaire. A brilliant scientist. A glowing secret beneath the sea. Dr. Mira Saeed has spent her life studying bioluminescence-the cold blue light of living organisms hidden in the ocean's dark. But when her Karachi laboratory is destroyed and victims begin appearing around the world with blue light glowing beneath their skin, Mira is pulled into a deadly conspiracy involving stolen science, designer drugs, private biotech empires, and an ancient mystery her father died trying to bury.
Enter Cassian Vale: impossibly rich, devastatingly handsome, and morally ruined. A spoiled playboy, criminal shipping heir, and suspected smuggler, Cassian is everything Mira should hate. He is arrogant, dangerous, ruthless-and the only man with enough power, secrets, and darkness to help her survive. Their hunt leads from Venice's masked luxury auctions to Dubai's glittering skyline, from Socotra's haunted waters to a hidden Maldives research facility where science and myth collide.
At the center of it all is Seraphim: a living blue phenomenon that responds to fear, records trauma, and may be far older than humanity understands. As Mira and Cassian battle a ruthless biotech visionary determined to weaponize fear itself, their attraction becomes as dangerous as the conspiracy surrounding them. Cassian may be a criminal, but beneath his cruelty lies grief, loyalty, and the possibility of redemption-if Mira can survive long enough to decide whether a monster can truly change.
Darkly romantic, cinematic, and filled with action, mystery, fantasy, luxury, betrayal, and forbidden desire, The Seraphim Tide is a complete standalone story with a powerful ending and a thrilling opening into a larger saga. Approximate length: 22, 000 words.
