Although The Hunger Games: Sunrise on the Reaping is centered on the story of Haymitch Abernathy, the book also has the chance to explore other plots, including this creepy Ballad of Songbirds and Snakes storyline. Young adult author Suzanne Collins recently announced that she is releasing Sunrise on the Reaping, a new installment in her iconic The Hunger Games book series. The story, which is set to debut in 2025, will likely follow a young Haymitch as he enters the 50th Hunger Games. A movie adaptation is also already in development. This is the second Hunger Games prequel.
