The secret of the past by Taghin Scowiss

When Josh returns to his hometown of Nightown, he plans a reunion with his old high school friends: Mikael, now a doctor and father; Tracy, a firefighter about to get married; and Brandon, happily raising his daughter with Hélne. However, Josh feels like the outcast, grappling with a haunting past—the unsolved murder of Eva Hargreaves, a girl who vanished during their high school years.

As old memories resurface, Josh becomes determined to uncover the truth behind Eva's disappearance, believing that his friends share the burden of guilt. But not everyone agrees; some are willing to do anything, even resorting to violence, to keep their secrets buried. As tensions rise, old loyalties are tested, forcing each person to choose a side in a deadly game where the past refuses to stay hidden.
