"To be like St. Herman of Alaska!" These words - a family joke once - were turning Martin's world upside-down. Catapulted from life in Boston to Newfoundland - otherwise known as "the Rock" - he wants nothing to do with his father's missionary dreams. Accompanied by his parents and his all-too-perky little sister, a summer of hard work is all that awaits. Or so Martin thinks... That changes the day he finds a bronze cross at a historic Viking settlement. A whole new world opens to Martin then: one of trans-Atlantic voyages, unanswered clues, suspicious antique-dealers, narrow escapes, mysterious deaths, and at its center an ancient cross and a manuscript poem. A burning question begins his search: Is the cross viking or from the fabled voyage of St. Brendan the Navigator? Now with the help of his sister and a local Newfoundland boy, the three of them race to unlock the mystery of an ancient treasure. But with the Old Wolf hunting them, it isn't about treasure anymore... it's about survival.
