One of the primary themes of "Linked" is the impact of social media on relationships. The novel highlights how social media can both unite and isolate people. The main character, Lincoln O'Neill, and his friends are initially excited to be part of the Link program, which allows them to stay connected and share their experiences with each other. However, as they begin to realize the extent of the program's surveillance, they start to feel suffocated and disconnected from each other.
