The trilogy of Barb consists of the stories Harry Potter and the Psychic Serpent, Harry Potter and the Time of Good Intentions and Harry Potter and the Triangle Prophecy.
In Harry Potter and the Psychic Serpent Harry makes friend with a serpent (Sandy) who accompanies him to Hogwarts. She has some foresight. Barb writes:
In Harry’s fifth year he gets a snake with the Sight. Hermione’s torn between Ron and Harry, who’s torn between her and Ginny, who’s torn between him and Draco Malfoy, who’s torn between her and loyalty to his father. Plus: a Prophecy, Animagus training, a Dueling Club, Snape’s Penseive, kilts, giants, house elf liberation and more!
In the second book Harry travels back in time only to create an awful parallel universe. While Ginny in the original universe Ginny is still with Malfoy and Harry with Hermione, in the alternate universe Harry takes up with Ginny and his best friend Draco with his sister. Barb writes:
During his fifth year, Trelawney did a Tarot reading for Harry. She told him he would have to make a choice that could „change the world as we know it.“ At the beginning of his sixth year, Harry chooses, and the world does change. Does it change for the better? If he wants, can Harry change it back? Or is giving Harry exactly what he wants Voldemort’s ultimate revenge?
The third book is quite dark. Ron is a werewolf with all the usual prejudices. Barb writes:
Harry’s 7th and final year of school. In a time of uncertainty, the Muggle world has found a source of comfort and stability. Only Harry suspects that it isn’t safe. Wizards are more concerned about themselves than Muggles since Voldemort’s return, but are only Muggles at risk? Will anyone listen to Harry? He must decide whether to make a sacrifice that will change him–and the wizarding world– forever.
All Stories are rated R. Harry Potter and the Psychic Serpent was nominated on The Goblets as Drama in the first Term. It made second place.
