The Book of Spies by Gayle LyndsRead about another entry on the list.
Ivan the Terrible’s mysterious Library of Gold has been spoken of but never found. Now, one of the library’s gold-gilded books turns up, The Book of Spies, and has everyone looking for the library. The CIA enlists rare-book curator Eva Blake to help them. When an attempt is made on her life, Eva turns to her friend, Judd Ryder, ex-CIA intelligence officer. Together they embark on a mission that covers most of Europe. Lynds has written more books with the team of Blake and Ryder at the helm but this is the one that started it all.
