On a lead from her friend A. B. Ravenhoof, Daring Do heads off to the Tenochtitlan Basin to recover the statue of the ancient god. But Daring's troubles are only just beginning as she is sent off on a commission to find the legendary Sacred Stones, items that once held the power to defeat Discord and were last seen shortly before Nightmare Moon was vanquished. The stones have appeared all across Equestria, and Daring Do now has to make her way throughout the land to find them all.
But someone else is interested in the Stones... someone who's slumber has been awakened, who wants to use the Stones to make himself the most powerful being in Equestria, and to take revenge on the one who imprisoned him...
Racing against an unknown foe, Daring Do will need to rely on her wits, ingenuity, and her closest companions. For as a cult of the ancient god rises in Equestria, it's hard to tell who she can trust.
