The Involves the Priory of Sion, the Sauniere family and the quest for the Holy Grail. The solving of the mystery results in the knowledge of ancient spells.

To the Rescue: Alternative Universe

This book is part of the „To the Rescue“ series but takes a somewhat other outlook. DrT writes:

James refused to consider allowing Harry to be taken to America should anything happen to both himself and Lily. What might have happened if Lily had gotten him to change his mind? After being raised in America as Henry and Tabitha�s step-son, Harry Potter returns to Britain to attend Hogwarts. His First year will be much the same, yet also very different.

Because Harry is raised in a loving environment he is able to destroy Quirrel/Voldemort at the end of his first year.
