Harry and his allies have won the war against Voldemort (read HP and the Goblin Rebellion and The War of Shades). Now it is time to get on with living, but Harry finds it more murky and conflicted than he is prepared for. In his search for a solution he encounters a greater danger than he had ever met before.
Seventh year - The scar connection becomes wide open, giving both Harry and Voldemort ever more detailed views into each other's mind. Harry works on practicing the message he gained in Egypt (Harry Potter and the Goblin Rebellion), but Voldemort launches the Second War to fill Harry with hatred and anger and to strip him of all who are loyal to him. Ever more desperately Harry trains himself and others to fight, but something is making all of his friends fight each other. Harry must find a way to stop the internal warfare or Voldemort will be able to launch an attack on Hogwarts that will destroy all who are capable of resisting him, including Harry. Through all this, Harry must learn for himself how he will finally vanquish Voldemort.
Year 6 - The goblins are threatening rebellion: Now that Fudge acknowledges Voldemort's return, he is pushing wartime policies, which oppress the goblins. Voldemort is seeking the secret in an ancient Egyptian magical site. Harry is being drawn into these two seemingly-unrelated developments. At the same time, he must train students in the schoolwide DA, while the burden of the Prophecy is filling him with visions, which cause Harry to pull back from his friends. But love has a way of arising whether it is welcome or not. For Harry, the course to resolution is never smooth, but if Harry can thwart Voldemort's plot, he can gain access to the secret which could enable him to use the 'Power the Dark Lord knows not.'
