I love one of us is next, and one of us is lying. There are both amazing books. One of us is lying concentrates on one theme in particular, Simon, where as one of us is next had more adventures and plot twists. The only reason I gave this book 4 stars is because of the ending. Now I don’t mind a little cliff hanger, like Karen’s other book ‘Two can keep a secret’, but the one in this book is very big and I feel there should be a third book. There is far to much that is left untouched such as some relationships, the actual mystery and why the person who helped with the truth and dare game did what they did and what happened to them after that. Apart from that this is one of my favourite books and Karen is one of my all time favourite authors. Keep going!
