Harry Potter grows up in a cupboard… until one ordinary morning turns into anything but.
Opening the door under the stairs, he doesn’t step into Privet Drive, but into the streets of New York at night—where a desperate boy almost gets kidnapped, and is instead rescued and adopted by Ben and May Parker.

In this new world, Harry awakens a terrifying well of “chaos magic” inside himself and catches the attention of the Ancient One, Sorcerer Supreme. Under her guidance in Kamar-Taj, he learns to wield dimensional power without paying the usual price, fights demons and hell-dwellers, and grows up alongside Peter Parker and Gwen Stacy.

Seven years later, a misfired portal drops him back into his original universe—into his eleven-year-old body on the very day of his Hogwarts letter. Armed with the experience of a near–Sorcerer Supreme, a debt to his exhausted teacher, and a very firm belief in progress and technology, Harry steps into Diagon Alley, only to find a stagnant wizarding world hiding behind outdated robes and crumbling bricks.

Between chaos magic and a wand, between Kamar-Taj and Hogwarts, Harry decides he won’t just survive prophecy—he’ll rewrite the fate of the wizarding and Muggle worlds alike, even if it means dragging wizardkind, kicking and screaming, into the future.
