This book is about a girl named Ivy who has discovered this anonymous art sharing app, VEIL, where you only see posts from people in a 5 mile radius. She happens to also have a lot more time on her hands because after returning from a "nerd camp" her best friend Harold has turned into a college obsessed freak, joining every club in school. Slowly but surely, Ivy discovers that some of her favorite posters go to her school and she begins to give them gifts. But of course, some things go wrong along the way. I mean it wouldn't be a proper novel if they didn't. I really enjoyed this book.
