Infinite Escape Rooms: I Reverse Death Endings Across the Heavens

Amber eyes reflect a secret room collapsing around her. Su Mi clenches the electronic watch left behind on the day her younger sister disappeared. The Heavenly Worlds System has trapped humanity in deadly puzzles, and if she solves every secret room, she’ll uncover the truth. That is, until a silver-gray-haired man tears off his disguise, the raven AI lets out a humanlike sigh, and the girl who calls her “big sister” reveals a clone number on the back of her neck. Now, she has to keep her head in a collapsing parallel universe: Is the System selecting agents, or has humanity long since become the plaything of a higher dimension? When the key to the final secret room slides into the lock, the wind whips her black hair around. Before her stands the plaza where her sister disappeared all those years ago. This time, she won’t run away.
