A great option similar to John Green novels is 'Stargirl' by Jerry Spinelli. It's about a unique girl who stands out in a conformist high school environment. The story has themes of individuality, first love, and acceptance, which are also common in John Green's books. It's a heartwarming and thought - provoking read.
The main theme is about self - discovery and the search for meaning. The characters are on a journey to figure out who they are and what they value in life.
