The edition 10-2019 of the SIYE Buried Gems brings you a story that starts at the end of HBP, Losing Each Other by MyGinevra.
Summary: This story follows Harry and Ginny from their parting after Dumbledore's funeral. Much of it is told from Ginny's POV. The first chapter, "Ginny's Mermaid," was originally posted as a one-shot. I have revised it slightly as part of this longer story, but it is essentially the same as it was when I first posted it.
The story was written pre-DH. If you liked Losing Each Other, then I'd recommend reading the 'kind of' sequels The Hogs Head and Ginny's House as well. 'Kind of' sequel because it keeps some elements of Losing Each Other, but instead of creating an alternate universe, it follows canon, including Deathly Hallows. The sequels start during the final battle and describe the start into Harry's and Ginny's life together.
Feel free to let us know what you think about this story!
