Red Mirror. Kingdom Chronicles, #4

The Vanir of the south speak of the Red Mirror, a legend hidden in the mists of time. In the desert of the Southern Kingdom, a grim message is left. No one knows who it is for, or why anyone would do such a thing. The hideous crime is being investigated by detective Cornell Nightworth and his partner, Jenny. The strange incident leads them towards the hidden history of the Last War, and towards someone thought long gone.
Just when they start to get somewhere, the case gets taken away from them. But Cornell is unwilling to let it go, and decides to pursue the truth using his own methods - no matter where it might lead.
