The Star Key

An ancient key. A Nazi hunt. A race to control time.

When Max returns with the Star Compass—an artifact capable of charting celestial motion—the clues point to a second relic: the Star Key.
Hidden for centuries and whispered through history, the Key is said to unlock the Compass's true power…
To bind time itself to the stars above.

Now the race is on.
From Nazi-occupied Athens to the vaults of Alexandria and a forgotten monastery high in the Alps, Max, Chloe, and Nick pursue a scattered chain of fragments—each holding secrets the enemy is desperate to possess.
The Abwehr is closing in, and what they intend for the Third Reich isn't conquest.
It's dominion over time itself.

As Nile ruins give up their secrets and alliances shift in the shadows, Max must decide how far he's willing to go to keep the Key hidden… or to wield it himself.
Because the Star Key doesn't just unlock the Compass.
It awakens it.

And some doors, once opened, cannot be closed.

The Star Key fuses history, danger, and breakneck adventure into the most cosmic Max Sterling mission yet—perfect for fans of Lockwood & Co., The Inheritance Games, and Artemis Fowl.
