The content of the book consisted of the events he encountered during his high school life. The book followed the life of Lucas Scott including his love life with both Peyton Sawyer and Brooke Davis, the friendship between himself and Haley James Scott, the close relationships he formed between his mother, Karen Roe, and his half brother, Nathan Scott. The book also chronicled the final years of Keith Scott and the rise and fall of his father, Dan Scott.
The book was based on Lucas' real life and chronicled his final two years of high school, the emotions he felt, and the hopes and dreams of himself, as well as those of his fellow students. It was overall based on his love life with his high school girlfriend and future wife, Peyton Sawyer; the book projected her as a noble, down to earth, creative woman. The book was written during his years at high school. They were written as they happened and written exactly how he felt at the time. Lucas kept writing during his hook ups and break ups with his girlfriends, even during harder times, such as the death of his uncle and happier times such as the birth of his half brother's child and the victory at the State Championship. His second novel, The Comet, was met with much less enthusiasm and was edited by Lindsey Strauss, who believed in the book. Eventually, Lucas and Lindsey began a relationship while working on the novel.
The novel was successful enough that it caught the attention of Julian Baker. He convinced Lucas to begin producing it as a film. Although the production seemed to be going well, with Lucas writing the script and working collaboratively with the director Adam Reese, the film was unsuccessful and failed to meet completion in the production process.
Lucas's novel was followed by a second, The Comet. Although this novel was not as successful as his original, Lucas maintained his status as a well-known author.
- "Lucas, I’m so proud of you, your words are wonderful. Don’t be afraid to share them with the world, follow through and finish this. Remember, there is a tide in the affairs of men.’ It’s Julius Caesar."
- "She was fiercely independent, Brooke Davis. Brilliant and beautiful and brave. In two years, she had grown more than anyone I had ever known. Brooke Davis is going to change the world someday, and I’m not sure she even knows it."
- "Suddenly, it was as if the roar of the crowd, the echo of the final buzzer, the cheers of my teammates were all sounding from a thousand miles away. And what remained in that bizarre, muffled silence was only Peyton, the girl whose art and passion and beauty had changed my life. At that moment, my triumph was not a state championship, but simple clarity. The realization that we had always been meant for each other and every instinct to the contrary had simply been a denial of the following truth. I was now, and would always be, in love with Peyton Sawyer."
- "Chapter Three. Peyton Sawyer is destined for greatness. Actually, she already is great. Because Peyton Sawyer has a thing called integrity. And nothing or no one is ever going to change that."
- "And in that moment he realized it’s not what you are or who you are, but who they allow you to be."
- The novel's title, An Unkindness of Ravens, is first quoted by Lucas to Haley in Pilot and later in Lucas' closing voiceover in The Games That Play Us.
- During the years between her separation from Lucas and her return to Tree Hill, Peyton Sawyer bought a copy of the book everytime she saw it. She stopped buying them not long after returning home, after discovering Lucas and Lindsey were engaged. She then burned her entire collection.
- It is believed the first four seasons of One Tree Hill catalogues the content of the book.
- Rachel and Lucas's encounter on the River Court was written into the novel, and can be found on page 88. ("Hold My Hand As I'm Lowered")
- Julian's idea to revive Ravens as a television series instead of a movie is reminiscent of Mark Schwahn's decision to make a television series out of the original One Tree Hill plot elements instead of a two-hour feature film, which was his first idea.
