James Moriarty hasn’t been the same since he enrolled at Baskerville Academy. During his first year, he was forced to room with the insufferable Sherlock Holmes, he grew distant from his younger sister, Moria, and then, horribly, his father died under mysterious circumstances. Now with school back in session, James has become more isolated than ever. And for the first time in her life, Moria isn’t sure if her brother is on her side. The only person she can trust is Sherlock. Sherlock listens to Moria’s problems and tries to break through James’s wall. He is obsessed, maybe to an extreme, with finding the truth about their father’s death. But at least Sherlock cares, and that’s why Moria joins him on a quest that leads to a secret sect, a rare jewel, and a murder that may change everything. The search for the truth is darker than even they could have anticipated. Rick Riordan, author of the Percy Jackson series, said, “Only a mastermind like Ridley Pearson could put such a fresh spin on Sherlock Holmes.” It’s another edge-of-your-seat mystery-adventure from New York Times bestselling author Ridley Pearson.
