SPOILER ALERT!

The Trials of Apollo

The Trials of Apollo, Book One: The Hidden Oracle - Rick Riordan

I think that The Trials of Apollo was a very surprising book. This book was surprising because I never expected Meg to leave Apollo and side with Nero after she had just saved the Grove of Dodona. I was also shocked by the group of Roman emperors, or Trimunitive, that were discovered to have survived centuries by attaining tribute from their followers and by providing support to those opposing Camp Half-Blood. One last part of the book that I was surprised by was when Leo Valdez returned to Camp Half-Blood and turned out to be apart of the new prophecy that Apollo had received from the Grove of Dodona.  And for these reasons I stand to believe that The Trials of Apollo was surprising.
