Right before their senior year, a group of close friends travels to Brazil for one last unforgettable adventure together. With one girl’s older brother acting as their chaperone, the group spends their vacation exploring everything Brazil has to offer before signing up for an exciting freshwater cave expedition. Led deep underground by an experienced guide, they enter a breathtaking maze of crystal-clear water and hidden caverns. But when they become trapped inside the massive cave system, their dream trip quickly becomes a nightmare. Something dangerous is moving through the water. Separated from the outside world and struggling to find a way back to the surface, the friends must rely on one another as fear, secrets, and panic threaten to tear them apart. With a deadly predator hunting them through the darkened caves, every decision could mean the difference between escape and disaster. By the time help finally arrives, only a few members of the group will make it out alive—and the survivors will never forget what happened Beneath the Blue.
