Tamsin Winter's Girl (In Real Life) is a gripping teen school story about the pitfalls of growing up online, which works for adults as well as children. The Bookshelf Sisters discuss the dangers of family vlogging, early access to social media, and how the Internet has changed our lives. We also feature contemporary sci-fi thriller More of Me by Kathryn Evans, which Chris thinks is even better than Beauty Sleep (discussed in Episode 2). But could it be the weirdest book Mary has ever read?
