In the age of Maya demigods, two carefree brothers are called to Xibalba, Land of the Dead. When they fail to return to the sea-ringed world above, One Hunahpu's firstborn sons are raised by their grandmother. Below, in Xibalba, One Hunahpu meets the rebellious Lady Blood, and their love leads to twin sons, destined to restore balance to the cosmos -- though they might need some trickster magic to survive the cruelty of their older half-brothers!
