When Dylan Stone disappeared in 1983, he left behind a worn journal and an impossible mystery.

Eighteen-year-old Dylan Stone and his best friend Bull Eastland set out on the adventure of a lifetime—a summer backpacking trip through Europe with nothing but a guitar, a journal, and Eurail passes. But a chance encounter with a desperate professor on a ferry to France changes everything. She entrusts Dylan with an envelope containing an old skeleton key and a cryptic poem—secrets tied to the long-lost Irish Crown Jewels, stolen in 1907 and never recovered.

From Shannon to Corfu, their carefree journey transforms into a deadly chase as shadowy pursuers close in. What begins as the trip of a lifetime becomes a race for survival—and ends in tragedy.

Forty years later, the mystery resurfaces.

Floyd Stone discovers his uncle's journal in a forgotten safe deposit box. Inside are clues to Dylan's disappearance—and to a treasure that has baffled historians for more than a century. Determined to uncover the truth, Floyd teams up with Bull's daughter Lisa and the retired professor who started it all. Together, they retrace Dylan's steps across Europe, following a trail of journal entries, long-lost letters, and dangerous secrets.

From the smoky pubs of Ireland to the sunlit beaches of Greece, their search uncovers a mystery far deeper than anyone imagined—and reveals that some secrets refuse to stay buried.

Dylan Stone's Journal is a dual-timeline thriller inspired by one of history's greatest unsolved crimes.
