Summary
In a future ravaged by war, Harry Potter watches his friends fall one by one as Hogwarts is reduced to ashes by the hand of the most powerful demigod in the world: Percy Jackson. With Hermione’s help, Harry is sent back in time to prevent the conflict between wizards and demigods from ever beginning. His mission is clear: find and kill Percy before he becomes the monster of the future.
When Harry awakens in the year 2018, something is wrong. Reality itself has changed. Timelines are colliding, people are forgetting who they are, and events that never happened are suddenly true. The very fabric of the magical and divine worlds begins to unravel and Harry realizes the time travel came at a far greater cost than expected.
Trapped in an unstable reality, he is forced to do the unthinkable: ally with Percy Jackson, his sworn enemy, to restore the balance of time. But as the two face horrors beyond myth and magic, Harry begins to see the man behind the legend and that might change everything.
Caught between betrayal, paradoxes, and long-buried secrets, Harry must choose: save the world… or destroy the only person who truly understands him.Series
