When twelve-year-old genius Ari Bini discovers a hidden lab beneath his school, a glowing circuit unlocks a mysterious portal—and a secret that could unravel the multiverse.

Ari meets Lyra, a girl from another dimension, who reveals his connection to the Starborn, protectors of all realities. But rogue experiments have begun collapsing worlds, and Ari may be the key to saving them—or destroying them.

With science, magic, and courage, Ari must master the Arc Core, survive impossible worlds, and stop a villain who wants to reset all existence.

The multiverse is calling.

And Ari's journey has just begun.
