内容简介：
Regan O'Reilly had a life-altering decision to make. Should she go on a fifteen-day trip through Italy with her crazy Aunt Lil, or should she stay at home and play it safe? Decisions this gigantic were tough for a timid twelve-year-old, but after lots of help from friends and family, a choice to try the trip was made. Gondola rides, secret passages, strange foods, and terrifying train trips were all parts of this new wild Italian adventure. Ever lurking in the background was a mysterious stranger with slicked-back hair and thick black glasses. Why was he sneaking around the palace in Venice, or hidden behind a camera in a museum, or sitting two rows up on the wrong train out of Florence, or most terrifying of all, following Regan to the top of the tower in Pisa? Why was he following her halfway around the world? What did he want? In Look Who's Watching, Regan finally got the answers to all her questions, became a world traveler, and emerged as a new and improved twelve-year-old.
