Trust No One by Linda Sue Park

This book finally started bringing the pieces together for the series finale (due out in March). Now I understand what the Vespers' goal is (other than torturing the captives and making Dan and Amy steal important things). I thought that there were a number of plot points that got dropped throughout the book--especially in reference to Amy's relationships with a variety of characters. I love the way this series picks up historical artifacts and mysteries and tries to tie them together--it's not always completely successful, but it is entertaining.
