Pena, M. (2013). Infinity ring book 4: Curse of the ancients. New York, NY: Scholastic Inc.
The fourth Infinity Ring episode sends time-traveling youths Sera, Dak, and Riq first back to the early days of the Mayan civilization and then forward 800 years to witness the fiery destruction of its native culture by the Spaniards. Carrying out their mission to save an ancient codex entails narrow squeaks aplenty and clashes with the archenemy, Time Wardens.
