Junglekeeper invites readers into the wild world on which all Earthly life depends—and, within it, into deeper truths about purpose, calling, and connection. Paul Rosolie, a kid from Brooklyn drawn irresistibly to the outdoors, finds himself in the Amazon, joining Indigenous communities in a fight to protect it from industrial threats. Along the way, readers encounter giant snakes, displaced jaguars, complex forest canopies, miraculous waterways, and uncontacted peoples defending their home. As Rosolie recounts how he and unlikely allies helped preserve over 80,000 acres of rainforest, he reveals the power of saying “yes”: yes to adventure, to danger, to sacrifice, and to discovering who we are between dirt and sky, among beings more mysterious and alive than we imagine.
