* "The Catcher in the Rye" by J.D. Salinger: This is the most prominent book Lucas reads. It's mentioned repeatedly throughout the series, often as a symbol of his rebellious nature and search for meaning. He even gives a copy to Brooke Davis.
* "The Great Gatsby" by F. Scott Fitzgerald: Lucas briefly mentions reading this classic in season 1.
* "To Kill a Mockingbird" by Harper Lee: Lucas brings this book to Haley James Scott's class when he's filling in as a substitute teacher.

It's worth noting that Lucas's love for literature is a recurring theme in the show, and he is often seen with a book in hand. However, the specific titles beyond these few examples are rarely mentioned.
The show focuses more on the emotional and character development of Lucas, using his love for reading as a reflection of his inner world and personal journey.
