Although the language in the Raven Boys isn't that difficult to understand—unless Gansey is throwing around his big SAT words—the actual storyline is convoluted and takes a savvy reader to unwind. There's a lot to keep track of when it comes to the history of the ley lines, all the people seeking it, and how the psychics' predictions ties in. It's almost like putting together a puzzle at times, but as you do, you see the full picture of how all of the different characters are interconnected. Totally worth the work, in other words.
