A windswept tree, the depth of a puddle, or a trill of birdsong could point the way home, and they still do—if you know how to look.With The Natural Navigator, his first book, Tristan Gooley invited us to notice the directional clues hidden all around: in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, growing plants, and habits of wildlife. A decade after publication, this modern classic still reminds us that we can find south by joining the horns of the crescent moon—and find adventure in our own backyards.","images":["https://cdn.shopify.com/s/files/1/0257/9447/products/9781615197149_3D-thumb.png?v=1677180214"],"price":18.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:55.147Z"},"share_url":"https://firestarter.network/l/lst_xL03T7EY","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
