As far as most of us know from the Rick Riordan assembly, the 39 Clues seemed like an average, run-of-the-mill mystery, the race for extreme power. But, from my point, in Book 2, things are getting extremely complicated, the story hatching from many different points of view.
At first, Dan and Amy Cahill have extreme trouble figuring out the clues. For example, here was clue 1, the simplest of all clues; RESOLUTION: The fine print to guess, seek out Richard S. (Do you know who Richard S. is? Here's a hint: think of Poor Richard's Almanack.)
Making things even more complicating are the vast distance between the clues, including smaller clues to the clues. What I have read is that Amy and Dan have gone through the Paris catacombs (Lisa may tell you about those), including a near miss at the subway (how would you like to have been run over by a train?).
With all these paths -- and potential shortcuts, maybe a little stealing -- you can never tell who's in first, and trying to follow another team could be the last mistake you ever made. You could go from last to first in an instant, and without knowing it, back to last.
