At low tide, the coast reveals a path. A few hours later, it disappears. Jonah, Deb, and Eli know how to read terrain. They know how to move across exposed rock, how to time a crossing, and how to adjust when the ground shifts beneath their feet. Along the Pacific headlands, the ground changes constantly. At low tide, long ridges of basalt stretch out into the ocean. Tidepools fill with darting fish. Sea caves open along the cliffs. For a few hours, the coast reveals a maze of routes that don’t exist the rest of the day. Their plan is simple: cross the outer shelves and camp on a flat stone that becomes an island when the tide returns. But the tide turns faster than expected. Surge channels fill without warning. Routes that existed minutes ago vanish beneath rising water. Now every decision matters. Because along this coast, the difference between a safe crossing and a trap is measured in minutes. Salt & Stone is the second book in the Trailmarked series—wilderness adventures built not on panic, but on skill, awareness, and the quiet confidence that comes from paying attention. Jonah reads terrain like a map. Deb calculates risk before it forms. Eli notices what the land is actually saying. Together, they move. For readers who love adventure grounded in real terrain, real skill, and the quiet thrill of moving through wild places. Start the journey with Book 1: Granite & Thunder.
