The first chapter of the fourth story in the "Moment of Impact," "Regards, Harry" and "One Man's Island" story arc has been posted (10/21/2011)
The title of this fourth story, "A Summer of Flotsam and Jetsam" is taken from the nautical terms. Flotsam is floating wreckage of a ship or its cargo. Jetsam refers to parts of a ship or its cargo tossed overboard to "lighten the load." This story takes place at Shell Cottage the summer after the Battle of Hogwarts. Harry and Severus are living together at the cottage. The story explores their relationship and healing, as well as the aftermath of the war and the battle on their friends and family, featuring Ron and Hermione, Minerva, Hagrid, Poppy, Luna, Neville, Andromeda Tonks, Teddy Lupin, Ginny, George and the rest of the Weasleys.
The new story can be read without the prequels but you can link to them from my profile page if you're interested.
