Henry Tyler wrote a 120-page mystery novel called Playback for his senior project. He was inspired by his love of mystery books from a young age. His facilitator, Farris Yawn, owner of a local bookstore, helped him with writing, editing, and publishing the book. Through the process, Tyler learned about challenges like writer's block and focusing for long periods. Despite difficulties, he ultimately found the experience rewarding and would consider writing another book applying his new skills and knowledge.
