A strange activation from the ancient time-traveling clock drops the team into the dark, watery depths of the fabled city, where glowing coral temples, futuristic relics, and ancient power clash beneath the sea.

But Atlantis isn't abandoned.

As a shadowy figure rises from the ruins and threatens to merge past and future for his own twisted gain, the team faces their most challenging mission yet. Can they solve the riddles of Atlantis before the city—and time itself—is lost forever?

The Lost City of Atlantis is Book Three in the Chronicles of the Timekeeper Detectives series, a gripping, fast-paced blend of history, fantasy, teamwork, and time-travel. Perfect for readers ages 8–12 who love Percy Jackson, The Magic Tree House, or Explorer Academy.
