When US border patrol agent Christian Rivera discovers the body of an undocumented alien in the middle of the vast Sonoran Desert with three enigmatic words carved into her flesh, presumably by her own hand, it triggers a frantic search for the remainder of her party: a group of 25 men and women who have inexplicably vanished into the desert.

Aided by two of the agency's best trackers, Rivera follows the woman's trail into the brutal heart of one of the hottest and most unforgiving landscapes on the planet, where nothing can survive for long. As more bodies turn up, Rivera and the others begin to realize they may be up against an enemy far deadlier than the desert, an unseen adversary that will stop at nothing to take from them what it needs to survive. A mythical evil that may not be myth at all, but horrifically real, could very well be stalking them, and their only hope of surviving the same fate that befell the missing party lies in deciphering the clues to their disappearance before it's too late - if it isn't already....

From Michael McBride, best-selling author of Burial Ground and Snowblind, comes Sunblind, a thrilling new novel of terror and action that'll take you on an unforgettable journey from the desperate streets of Mexico, through the deadliest corridor in the world to a place where mankind was never meant to tread.
