End Zone
End Zone is Don DeLillo's second novel, published in 1972.
It is a light-hearted farce that foreshadows much of his later, more mature work. Set at small Logos College in West Texas, End Zone is narrated in first person by Gary Harkness, a blocking back on the American football team during the school's first integrated year.
