There's no way to know exactly who the main characters are without reading the 'trust no one novel'. But it could have a young adult as a main character who enters a new and dangerous environment, like a boarding school with a lot of secrets. This young character would start out trusting people but as they discover more about the place, they learn to trust no one.
