Here's an Opportunity Novel

Gates across Earth have unleashed interdimensional monsters, bringing humanity to the edge of extinction with only a decade remaining. Armed with the awakened abilities Record and Time Rabbit's Luggage, a protagonist has endured seventy-six lifetimes of grueling regressions in desperate attempts to prevent catastrophe. Now, on this final attempt, the endless cycle of repetition concludes. Refusing to bear this burden alone, the protagonist offers others a chance to help change humanity's fate. Though framed as an opportunity, it comes with a price. As the protagonist reveals with characteristic confidence: they will provide a valuable opportunity, one that represents a bargain for what is being offered. The question remains whether others will accept this mysterious deal to alter the course of their doomed world.
