Katie Ellison is not a liar. It's just that telling the truth is so...tricky. She knows she shouldn't be making out with a drama club hottie behind her football-player boyfriend's back. She should probably admit that she can't stand eating quahogs (clams), especially since she's running for Quahog Princess in her hometown's annual Quahog Festival.
Kari and Lucas had two run-ins with a snarling painter who appears to be copying Rembrants. Using the kind of ingenuity and determination that only two teenage girls could come up with, Kari and Lucas embark on an international adventure to figure out who the mystery painter is and what he's up to. But neither is prepared for what they find. Suddenly what began as a madcap pursuit becomes deadly serious. Will they risk their lives in the name of art?
When Kari and Lucas first see Seneca Crane up on stage, playing the piano in front of hundreds of people, they are in awe. She is beautiful. She is amazingly talented. And she is only thirteen! But then they get to know her at the Edinburgh Arts Festival and realize that she envies them. Soon the three are becoming friends...until Seneca disappears. There's no stopping Kari and Lucas from jumping on the trail and tracking her down. Even when it leads to the heart of the Scottish highlands!
