The Foundation of Heaven is a historical fictional work about the fall of the Aztec Empire (old Mexico). Using his familiar style of mixing historical narrative with literary fiction, author D.H.C. Carter takes us into the world of the early 16th century and shows the collision of cultures that takes place between the old world and the new. Historic figures such as Cortez and Montezuma are brought into focus and their relationship is explored. Once again, Carter uses fictional characters to bring this story to life, leading the reader through the treacherous turns of the story of Spain's conquest of old Mexico.
