Religious visions. An artifact. A desperate quest. A rosary, once passed from Queen Isabella of Spain to King Charles, disappeared long ago. While Queen Isabella possessed it, she claimed to receive spiritual visions from the Virgin Mary—visions which may have begun the Inquisition. Chyna Stone and her remaining Found History team partners go on a quest for Queen Isabella’s rosary. While it’s believed to possess great spiritual power, legend has it that anyone outside her bloodline who touches her rosary will go mad. Even though she’s worried that her former boyfriend, Tony—and the Illuminati Reborn—might be planning something against them, when Chyna and the Found History team hear reports of a growing disturbance that mimics the legend, they fly to Cordoba to seek the Rosary of Isabella. The team hotly pursues the trail of those who seem to have fallen victim to its reputed delusions. They meet a journalist, Tacho Villanueva, who tells them he is also investigating religious visions, hallucinations, and the growing madness in the streets. The Found History team joins Tacho and they discover three bodies—and the police want explanations. The rosary hasn’t been seen since the time of King Charles. But Chyna is in a hurry to recover it from its current possessors before it’s too late—there’s a good chance that whoever possesses it will end up not only mad, but dead, too. As the team gets closer to recovering it, Chyna Stone proves she’s no ordinary archaeologist—she’s an intrepid adventurer, too—but will she also succumb to madness while seeking the Rosary of Isabella?
