I suck at blurbs, so here goes nothing. Please give it a chance though!
Meet Lynn Goodman. The typical high school nerd. She is happy enough. She has her dad, and her younger sister, Kate. Kate is a fifth grader, and Lynn is a Junior. She can't wait for school to be out for the summer. She has already planned out her three months off with new books, writing, and movie marathons. Then, she gets a new neighbor. His name is Duke, and he lives with his sister and her husband. He is also a junior, but he seems... Different. He, for some strange reason, seems to avoid everyone. No socializing. Nothing. That was odd, seeing as having a social life has always been a very important part of high school. Then, Lynn and Duke are partnered together for a history project. When they were working on their project at his house, she... accidentally looked through several photo albums, then, she sees that they are all filled with pictures of her. Some are even in clothes and places that she has never been. What is going on?
