Headspace OS: The Complete Book Bundle — three illustrated books plus a signed letter from the Professor.

• The Core Rulebook: The Operating System for Your Mind (397 pages)

• The Essential Upgrades DLC (307 pages)

• The Headspace OS User Manual (38 pages)

Two ways to play. Attach the books to any AI chat and say “Start Headspace OS.” Or play the app at headspaceos.com: no Grok or ElevenLabs subscription is needed, because Sparks pay for the built-in AI and voices.

The app plays in your browser, so each device and browser keeps its own Sparks Vault, and Sparks bought on one device stay there.
