I actually started out reading Legends of the Samurai by Hiraoki Sato but because the book was heavy in terms of content, I decided to read The Lost Symbol.
The Lost Symbol involves the story of the Masons and how a man, Malakh, strive to possess the society's ultimate secret. In his endeavor, Malakh had kidnapped Peter Solomon, a high ranking Mason and Robert Langdon's good friend. Malakh then had forced Langdon to solve the mystery in order to acquire the secret in exchange for Peter's life.
Well to me, Angels and Demons was more gripping than The Lost Symbol. So my rating: 3.7/5
