Towers of Heaven

Humanity got a century of the towers — monsters, floors, waves — and lost. Granted one wish at the bitter end, the last survivor spends it on a do-over: back to the day before the towers opened, carrying everything he learned the first time.

Progression: regression-powered climbing — foreknowledge of floors, skills, and mistakes turned into speed.

Reader fit: you want second-chance apocalypse prep where the deadline is known and every shortcut counts.

Texture: urgent, straightforward, save-the-world simple.
