Nico and the Niners - Kingdom of Shadows

If the dead can't hurt the living, then what is happening? After a traumatic event at his school, Nico must investigate the reason behind spirits killing people. He was told the rule is clear: the dead don't harm the living. However, this rule is being broken, and the barrier between life and death is weakening. Supernatural events are spreading through Recife rapidly, and chaos is gradually taking over. Nico might hold the key to uncovering the cause of the impending terror, but his friends may pay the price for it. A race against time begins, and the biggest challenge for the group is staying alive in a world being overrun by the dead. A hidden figure seems to be behind it all, manipulating corrupted souls like puppets. What is happening? Who is responsible for breaking the most important rule? Who is the man behind the Kingdom of Shadows?
