When the stars align, the countdown begins...
In their most cosmic journey yet, Ella, Liam, Mia, and Aiden are propelled by the ancient time-traveling clock into the heart of the Mayan Empire—an age of towering temples, starlit rituals, and celestial prophecy. But something is wrong in this ancient world. The stars are not where they should be, the skies have gone dark, and an astronomical event threatens to unravel time itself.

As the team deciphers cryptic inscriptions, explores jungle ruins, and faces a society on the brink of cosmic panic, they uncover a plot more complex than any they've faced before. With Dr. Morland hot on their trail, can the Timekeeper Detectives unlock the secrets of Mayan astronomy and reset the stars before history collapses?

The Mayan Astronomical Mystery is Book Four in the Chronicles of the Timekeeper Detectives, a middle-grade time-travel series filled with action, mystery, ancient cultures, and teamwork. Perfect for curious readers ages 8–12 who love Explorer Academy, The Kane Chronicles, or Treasure Hunters.
