Sacrifice to the Evil God

A rather rough blurb:

-

As she lay dying, his mother repeatedly warned him not to return to X Island.

Never. Go. Back.

Even though all his memories from before the age of fourteen were from the island.

As he stared in shock, his uncle hurriedly closed his mother's still-open eyes. In a mournful voice, he said, "She's gone, child. She was only talking nonsense."

But he could clearly sense the madness and malice in that gaze.

Then the cold hands of a merfolk creature pinned him in its arms. Its sharp fangs cut the skin beside his ear, drawing bright red beads of blood like roses.

The air was damp with mist. His thin shirt clung to his waist, revealing a faint, delicate curve.

Fear filled his eyes. His lips trembled as he thought, Something must have gone wrong.

It had to be...
