The Glitch Historians. Shadow World Paradox, #1

The story follows a group of thirteen-year-olds who discover they have a unique "brain-glitch." When they get close to one another, their personal feeds cross-wire, allowing them to see "ghost data"-deleted memories, hidden secrets, and private moments from people in their community that were supposed to be erased forever. The teens realize that the "perfect" adults in their lives are hiding a massive conspiracy within the digital archive.
They decide to use their glitches to become underground "Historians, " uncovering the truth behind their town's history. However, every time they access the ghost data, they risk their own memories being overwritten or corrupted by the very secrets they are trying to expose.
