Land of Burning Heat — Judith Van Gieson

Archivist Claire Reynier may have a priceless find on her hands. A woman named Isabel Santos has discovered a faded document hidden for hundreds of years under her family's adobe house. It could be the controversial last words of a Jewish mystic condemned to death by the Inquisition in Mexico City.

But before Claire can establish the letter's authenticity, it disappears, and tragedy visits the Santos family. Uncovering the history of a dark and dangerous past may bolster Claire's career...at the cost of her life.
