"End of the Line" by Layla Cole

College roommates Cory and Julian were in Mexico on spring break when "the Blight" moves across the U.S. causing entire cities to disappear and mutations in surviving humans.  They try to outrun it by going to Idaho and then Oregon, but the bright green light keeps getting closer.  With death appearing to be imminent, Julian makes a decision about his true feelings for Cory.  Will they face the Blight together, or will his revelation tear them apart?  I found the story a little hard to follow until about the last fourth, but the surprise ending makes up for it.  69 pages (Kindle edition).
