A Nazi journal. A miraculous medicine. A visionary scientist. As Carly Stuart searches for the Holy Grail, she discovers a cutting-edge research laboratory where sickening secrets-and astounding answers-abound.

Despite the danger Carly Stuart faced at the end of her first semester at Nassauton, she, Blane, and her professors plow ahead with their Grail quest. With new artifacts in their possession and questions about Grealia Eternae, Carly and her team set out in search of answers.

Their journey leads them to GE Pharmaceuticals and its ambitious CEO, who dreams of developing a drug to cure cancer and offer immorality. As the Fearless Foursome digs deeper, Carly learns the lab will stop at nothing to obtain the source of the drug's key ingredient-the Holy Grail itself. Carly must stay one step ahead of her enemies, because if she doesn't, and they get the Grail, there will be catastrophic consequences for the world.

But with evil lurking around every corner and self-doubt eroding her convictions, will Carly find the faith and fortitude to persevere?
