William F. Nolan 
Logan’s Run: Black Flower #1 

This epic adventure picks up where the famous novel left off. Logan has found Sanctuary a challenging existence. It’s not the Utopia of Runner myths. He jumps at the chance to take on a dangerous mission to destroy Hourglass, the facility that controls the palm flowers-the implanted device dictating how long each person may live. However Hourglass is now under the control of another former Sandman-the ever dangerous Gant.
