The Crossing, publicized as the second installment of McCarthy's Border Trilogy, is the initiation story of Billy Parham and his younger brother Boyd (who are 16 and 14 respectively when the novel opens). The novel, set just before and during World War II, is structured around three round-trip crossings that Billy makes from New Mexico into Mexico. Each trip tests Billy as he must try to salvage something once he fails in his original goal.

The Border Trilogy, which began with All the Pretty Horses, concludes with Cities of the Plain. Skryť popis
