Cults! Manipulation! Friendship! These three might seem unlikely bedfellows, but in Rebecca Wait's second novel, The Followers, there they are, all together. On the face of it, Rebecca's book is a story about cults and the manipulative powers of those that put themselves in charge. But more than that, it's also a book about the friendships that keep us afloat. Here, she talks about the relationship with one of her own friends which she drew on for the novel.
