1: The Last Chance by Ben If you have ever felt disappointed at how Harry simply accepted Dumbledore's actions and how the teachers at Hogswart allowed students to be bullies and showed their own biased nature then this and Ben's other HP fan fiction is a welcome retelling of the stories.
2: Sparks by black_coffee This story and the sequel "The Gunny and Lenore" provide an excellent mix of action, adventure and romance with the sort of real life detail that makes you want to keep reading. Can't wait for more.
