House of De Zavala - Black Heart Stone

Mike Lowrie

Based on actual events and true Texas history, The Legacy of the Black Heart Stone is a fast-paced thrill ride through Texas and Northern Mexico, fraught with danger and featuring a magnificent cast of unpredictable characters led by Luis De Zavala, a rookie archaeologist and direct descendent of one of the Founding Fathers of the Republic of Texas.

In his quest to find and protect valuable historic artifacts, including the highly-prized stone—if it even exists—he must stay one step ahead of an angry Mexican drug cartel, law enforcement officers, and his arch-nemesis, an established archaeologist with questionable ethics.

A high-octane adventure story that would do credit to Indiana Jones.
