Current adventure:

THE THIRTEENTH KEY

A forgotten explorer left behind a warning. Someone made sure it stayed hidden.

Seventy-three years after explorer Evelyn Vale disappeared, an apprentice archivist discovers a sealed box containing evidence that history got her story wrong.

He needs help.

Across twelve chapters, the reader works alongside Alex Mercer as his Second Investigator—following maps, studying photographs, decoding messages, testing evidence, and uncovering the truth behind a secret society and its missing thirteenth key.

ONE STORY. 12 CHAPTERS. EVERY CLUE CONNECTS.

A vintage photograph shows a dark wooden box labeled 'Evelyn Vale - Expedition Notes - Sealed May 17, 1953' next to an ornate antique key with a circular head and twelve pointed rays, all placed on a textured surface. The photograph itself lies atop aged, torn nautical and geographic maps with handwritten notes and illustrations.
