could see the pale square of the porthole door, receding in the distance, but try as she might, she
couldn’t kick her way toward it. The current was too strong.
Hopelessly, she looked up. Her witchlight stone was gone, sinking through the water below her.
The light from the ever-receding porthole lit the area around her, but she could see nothing but
darkness above. Her ears were popping. Raziel only knew how deep down she was. The water near
the porthole was pale green, the color of jade, but everywhere else it was black as death.
She reached for a stele. Her lungs were already aching. Floating in the water, kicking out against
the current, she jammed the tip of the stele against her arm and scrawled a Breathing rune.
The ache in her lungs eased. With the pain gone, the fear came crashing in, blinding in its intensity.
The Breathing rune kept her from struggling for air, but the horror of what might be around her was
nearly as intense. She reached for the seraph blade in her belt and pulled it free.
Manukel, she thought.
The blade came to life in her hand, spilling out light, and the water around her turned to murky
gold. For a moment Emma was dazzled; then her vision cleared, and she saw them.
Demons.
She screamed, and the bubbles rose up around her, silent. They were below her, like nightmares
rising: lumpy, slippery creatures. Waving tentacles crowned with jagged teeth flailed toward her. She
swung Manukel and severed the spiked limb reaching for her leg. Black blood exploded into the
water, billowing up in clouds.
A scarlet, snakelike thing shot toward her through the water. She kicked out, collided with
something fleshy and soft. She gagged on revulsion and stabbed downward; more blood spilled. The
sea around her was turning to charcoal.
She kicked up toward the surface, carried on a billow of demon blood. As she rose, she could see
the white moon, a blurred pearl on the surface of the water. The Breathing rune had burned off her
skin; her lungs felt as if they were collapsing. She could feel the churn of water under her feet, didn’t
dare to look down. She reached up, up toward where the water ended, felt her hand break the surface,
the chill of air on her fingers.
Something caught at her wrist. Her seraph blade fell from her hand, a glowing point of light that
tumbled away from her as she was hauled to the surface of the water. She gasped in air, but it was too
soon. Water filled her lungs, her chest, and darkness slammed into her with the force of a truck.
