My steps stopped. The heavy skirt of my white sea-silk wedding gown settled around my feet as another sound came from inside-the wet, rhythmic slap of bare flesh.
A sickeningly sweet scent seeped through the narrow opening. Deep-sea blood-algae incense. An aphrodisiac favored by Inner Atoll nobles.
I reached the door without making a sound and pushed it open another inch.
Dim light spilled out, followed by ragged panting and the violent creak of the coral bed.
My breath caught in my throat. I bit my bottom lip hard enough to taste blood and pressed my eye to the gap.
On the carved coral wedding bed, two naked bodies writhed together. Gideon's broad back was unmistakable. Beneath him, Cristal's light chestnut hair tangled across the pillows, while the silver seal of House Gould hung from her discarded belt. My adopted sister-the woman who had stolen credit for my healing potions for years-was fucking my fiancé on my wedding bed.
Cristal dragged her fingernails down Gideon's back. "You keep mocking her, but she survived the Outer Shoals. What if she expects to follow you into the open sea after she becomes your wife?"
Gideon laughed against her neck. "She survived because she stayed inside one of the dry Tidal Bubble cities and walked around on human legs. Aiyana has no Tide-Spirit. The moment she crosses the barrier, she cannot grow a tail or open her gills. Without a sealed submersible coach, she would drown like any human."
"Then why marry her at all?"
"Because House Glass requires it," Gideon grunted. "She will be my wife in name only. She will never share my bed, wear my family's ring, or stand beside me before the court. Those privileges belong to you."
My fingernails dug deep into my palms, yet no tears came.
The ash-gray Brow Scale embedded in my forehead marked me as Spirit-less, while my bare fingers carried no Tide-Oath Ring to grant me rank, inheritance, or even a legal voice. Gideon had not bothered to give me so much as the cheapest bronze betrothal ring.
He had mistaken my lack of power for a lack of spine.
One corner of my mouth curled into a freezing smirk.
Crying like a wronged bride would only give Cristal the show she wanted. I quietly eased the door back into place, sealing the lovers inside, and turned toward the heavy bronze wall lamp beside the bridal chamber. It burned with deep-sea phosphor fire harvested from the high-pressure trenches-a blue flame that even seawater could not extinguish.
I lifted the cold bronze lamp from its bracket and tilted it toward the doorframe. The blue phosphor flame caught the hanging siren-gossamer curtains. Like starving vipers, the fire shot up the lintel, casting blue shadows across my expressionless face as thick smoke drowned out the aphrodisiac incense.
I hurled the bronze lamp onto the marble floor with an ear-splitting crash.
"Fire! The bridal chamber is on fire! Somebody help!"
Inside the room, the rhythmic creaking stopped, replaced by Gideon's panicked curses and Cristal's muffled shriek.
An alarm conch began to howl through the estate. Footsteps thundered toward me from both ends of the corridor as servants and Perimeter Vanguard guards rushed to the chamber carrying rune-woven fire blankets and urns of smothering trench sand.
I caught the nearest ceremonial attendant by the arm and shoved her toward the stairs.
"Lord Gideon is trapped inside! Fetch First Madame Caro!"
The attendant fled, screaming for help. I stepped into the shadows as the guards surrounded the burning doorway. Moments later, heavy footsteps struck the marble stairs. Gideon's mother, Caro Levine, appeared in a velvet gown, her face twisted in terror for her only son.
