Copanatec is the second book of the series The Timecrack Adventures, which sees the two young brothers, Archie and Richard Kinross, return to New Earth in the next dimension, in the continuing search for their parents who disappeared from an archaeological site in the Yucatan jungle. The island of Copanatec is home to The Lords of the Cloud, an ancient civilisation, who in their desperation to find a lost, life-giving treasure, have recruited Talon the Slave Master and the brutal Terogs to find it in the tunnels below the pyramid, before it is too late. Archie and his friend, Kristin, along with the villagers from the mainland of Amasia, are taken by the slave traders and forced to work in the tunnels below the pyramid to find the treasure. Richard, back on Old Earth, discovers Archie is missing, and along with Chuck Winters, a security specialist, set out on a journey to the next dimension to find him. The adventures with its mix of ancient cultures and time travel to new worlds in other dimensions, will appeal to young adults and older readers, alike.
