Robert Langdon has been summoned suddenly to give a speech for his friend and mentor, Peter Solomon, at the Capitol building in Washington D.C. It turns out to be a ruse set up by bad guy Mal'akh who has kidnapped Solomon. To get Solomon back, Langdon must provide Mal'akh with the Masonic Pyramid that leads to finding the Masonic treasure buried beneath Washington D.C. Also key to the story are Solomon's younger sister, a noetic scientist, the CIA, and, of course, the Freemasons.
For a fast-action plot, the story moved slowly for me. I didn't care for any of the characters, including Langdon. The back story for Mal'akh and his obsession with the Solomon family got tiring, but I do admit that I was surprised with the final details.
I thought there were two endings to the story. Catching the bad guy and finding out who he really was and his motives for murder, kidnapping, and all around evil mayhem was the first ending. The final 100 pages was about the mystery of the Masonic pyramid. If anything, The Lost Symbol made me want to learn more about whether and how the Freemasons may have influenced our country's Founding Fathers.
The Lost Symbol is one of the books I'm reading for the Off the Shelf Challenge.
