From the Flame to the Spark by Nightboy, is a Peggy Sue Fanfic from the Harry Potter fandom that features Ginny Weasley as the only time-traveler, though other characters are affected by fragments of the future that comes back in Ginny's wake. Features a believable determinator!Ginny, hardened from leading the DA during the year Harry was Undesirable No. 1, who doesn't even attempt to keep events close to the original timeline.

Includes a muggleborn OC in a minor role, who ends up with the adult Ginny's magical core as well as some of the magic of the Room of Requirement, loves DC Comics, and comes to all the wrong conclusions about what having powers means he is. From the Flame to the Spark is not actually a crossover with Teen Titans.
