Faced with a mysterious, deadly fog bank in a seaside Scottish village, new friends Nolie and Bel look for ways to stop it--coming across an ancient spell that requires magic, a quest, and a sacrifice. Nolie Stanhope is spending the summer with her scientist father in the tiny Scottish village of Journey's End. He's studying the Boundary-- a mysterious fog bank offshore. Bel McKissick's family's livelihood depends on the tourists drawn by legends of a curse: going into the Boundary means you'll never come back. Then Albert Etheridge, a boy who disappeared into the Boundary in 1914, returns, without having aged a day and with no memory of the past hundred years. And now the Boundary is creeping closer to the town....

While Nolie's father came to the town of Journey's End to study the Boundary, a mysterious fog bank offshore, Bel's family can't afford to consider it a threat. The McKissick's livelihood depends on the tourists drawn by legends of a curse. Still, whether you believe in magic or science, going into the Boundary means you'll never come back.
