Shadow in the rainforest

Four experts. One deadly mystery. When a string of gruesome animal mutilations shakes the mountains of Puerto Rico, four specialists from Chicago are sent deep into the heart of El Yunque rainforest. But what begins as a scientific investigation quickly unravels into a nightmare of blood-draining predators, government secrets, and ancient folklore brought to life.Tensions flare as the team faces not only the horrors lurking in the jungle, but each other's buried agendas. Every shadow could hide the creature they've been hunting-or something worse. Survival means navigating betrayal, confronting impossible truths, and outrunning a force that doesn't just kill... it feeds.And in the end, one of them will have to make the ultimate sacrifice to keep the darkness from spreading across the world.
