Now carrying the title of Lapis's Witch, Meg heads to an elite event feeling like a full-fledged magic user. Held once every twenty years, the Rite of Witchcraft boasts the latest in magical innovation, and everyone is focused on curing one of the world's deadliest diseases: magical contamination. After the convention, Meg heads back to Lapis to find the town's sacred tree suffering from that exact affliction. The Spirit inhabiting the tree wishes to give back to its beloved town, but as the contamination worsens, Meg must find a way to cure the uncurable. Her heroic efforts draw the attention of another of magic society's strongest sages--the greatest doctor in the world, the Sage of Vitality. As Meg begins to unravel the history of witchcraft, more puzzle pieces fall into place. Still, only six months remain until her time runs out. Can she find a way to undo her curse before it's too late?!
