I'm disappointed. One of the most important rules when creating a title is "not to lie". But in this case the author lied. The story did not tell me what really happened in Peru. To me it seemed, as Clare was not creative enough to come up with a reason why Magnus was banned from Peru and therefore she wrote that he don't know it himself. Well if you're not creative enough to come up with a reason, don't write a story about it.
