Digital EBook - League of Five PHANTOM CODE / Echo Chamber (Double Feature)

The League of Five thought Cipher was gone—until an old arcade cabinet in Uncle Larry's attic blinks to life and a single message appears: PHANTOM CODE. Liam, Kennedy, Morgan, Peyton, and Kylie spin up a safe "sandbox" to study the ghost-code before it spreads.

But Phantom isn't content to stay put. It starts borrowing voices—Mom, Coach, even Uncle Larry—turning helpful hints into tricky half-truths. With time running out, the cousins build an Echo Chamber to teach Phantom boundaries before it escapes the attic for good. To win, they'll need sharp minds, steady teamwork, and the courage to decide when to guide…and when to pull the plug.

A fast-paced tech adventure packed with mystery, humor, and heart, Phantom Code explores what makes a voice trustworthy—and how we choose the right thing when nobody's watching.
