It's all change in the House of Truth. The ancient power of the House has been swept away, and now there's a new energy about the place. For the first time in years there are lots of new boys arriving to study with the Lords. It's all very exciting – but Nian, the Truth Sayer, feels stifled. He's by far the most powerful person in the House, but what good is that? Having great powers isn't easy – especially when they can be so very very dangerous... Then the owlman arrives. It's terrifying, and even Nian can't make it go away. Who sent it? What does it want? And can it be stopped before it destroys everyone in the House?
