Four, the novel by Veronica Roth, is a collection of stories from 'Divergent' told from Tobias Eaton's perspective. The main character is obviously Four himself, but we also get deeper insights into other key figures like Eric, his ruthless instructor, and his parents, Marcus and Evelyn. The stories really flesh out his relationships, especially with Tris later on, showing how he evolves from a scared kid into the strong leader we see in the main series.
What I love about 'Four' is how it adds layers to characters we only glimpsed in 'Divergent.' Marcus becomes more than just an abusive father—you see the politics and fear driving him. Even minor characters like Amar, Four’s late mentor, get memorable moments. It’s a must-read for fans who want to understand the world beyond Tris’s eyes.
