Frontera
(Book)

Mateo knows that he can survive the trek across the Sonoran Desert that will take him from Mexico to the United States. That is until he’s caught by the Border Patrol only moments after sneaking across the fence in the dead of night. Escaping their clutches comes at a price and Mateo is lost in the desert without a guide or water. With the odds stacked against him, his one chance at survival may be putting his trust in something, or rather someone, that he isn’t even sure exists, a ghost named Guillermo.
