The Timekeepers are a secret organisation of kids who keep the course of history on track – and history needs them – a villain called DeLay is causing chaos! When the hands on their watches start to spin backwards, the Timekeepers know that DeLay has been up to no good, and it’s up to them to put things right…

In this instalment, the Timekeepers travel back to 1442 and the Aztec Empire! Rosa is very excited to see the time of the Aztecs, who lived in the land that is now called Mexico. She and Luke are in the magnificent Aztec capital, Tenochtitlan, and explore its enormous stepped pyramids, impressive aqueducts, and bustling markets, with traders selling chilli peppers, feathers, turquoise, and fabric with geometric patterns.

With a range of adventures that span all of history, The Timekeepers series is perfect for any adventure lover.
