Lost Symbol information on Twitter: @lostsymbol
At his 'Key to the Lost Symbol Clues' blog, Mark Koltko Rivera has posted what seems to be the first review of The Lost Symbol, albeit in Norwegian (Google translation here). Plenty of speculation that the review was a hoax, or just based on previous information, but latest evidence suggests that it is genuine. Amazingly, the 'Paul Maier' link turns up again, seemingly in a credible way!
Also, note that Parade and various UK newspapers (such as The Sunday Mail ) will be featuring the first two chapters from the book today, so we should all get a better idea of the vibe of the novel soon enough.
