Whilst Harry recovers from his victorious battle with Voldemort, the Order struggle to round up the remaining Death Eaters. With Tom Riddle's followers at large, the wizarding world is threatened once again. Will Harry take matters into his own hands to rid the world of evil? Or will he finally accept that he is not alone. Sequel to The Enemy Within.

After an attack on the Hogwarts Express leaves Harry with a severe head injury, he struggles to make sense of the strange things that are happening to him. With help from Remus and Snape, he must figure out what's wrong and prepare for the final battle.

Harry is left alone with a hungover Tonks and a bottle of firewhisky. At the time, trying to show that he can infact handle his alcohol was a pretty good idea.
