Green Abyss – Rise of the goblins

Valtira, Serena, and Lyria are elite operatives of the Sisterhood of Chains, sent on a rescue mission that turns into a trap. A goblin shaman with unstated ambitions takes them instead, and the story that follows is unhurried and unpleasant on purpose.

Chained underground with their magic sealed by ancestral runes, the three women are put through a "training" designed to wear down whatever made them elite in the first place. The narrative sits in the gap between resistance and surrender, and it doesn't rush to close it.

This is a kinetic novel, so there's nothing to click except forward: no choices, no branching paths, just the story playing out at its own pace. The menu does let you fiddle with text size, color, and textbox transparency, which is about as much control as you're getting.
