by Mike Wells
When Briana challenges Kyle, her best friend, to a dangerous swim across the lake, she discovers an underground spring that contains a magical substance: the "green water." The mysterious, glowing liquid heals any physical wound, triggers a heightened sense of awareness, and evokes superhuman abilities. But there is a catch: once you drink the green water, you are addicted forever.
