The first book in a new series about neighborhood friends who find sudden fame with a series of viral videos... only no one knows who they really are. Sophie, Harper, Luke, and Gus: four kids from the same neighborhood, lifelong friends, throw on some costumes and make a funny video one night when their parents are out. One of them shares it with the group, another posts it on a TikTok-like social media, and suddenly the video blows up. Which makes the kids famous! Well, famous... and anonymous. Because no one can tell who they really are-- and their parents must never find out. But their new fans want more content! So the four friends go on to make a series of over-the-top videos that vault them into a new world of celebrity and influence. They feel the rush of attention and the power of their own creations, but also struggle to preserve their fame and their anonymity. These books explore friendship, loyalty, and imagination, all while considering big questions that come up in a social media context, like: How do you protect your true self online? And is it ever really possible to be anonymous?
