This is one of those books that I 
feel like I stole because I only paid 99¢. The story begins with a flu 
pandemic. Then an alien space craft appears over the ocean in Southern 
California. It quickly becomes apparent they brought the plague.
There are three main characters--Walt, who decides to walk from New 
York to California after his actress girlfriend dies from the flu--and a
 married couple, Raymond and Mia, who do their best to survive right 
under the glare of the alien mothership. Walt is by far the best 
character. He starts off as a doubtful, suicidal wimp and over 3,000 
miles turns into the hero who doesn't care about being a hero. His 
sarcastic  of humor lends some real brevity to the story.
The 
descriptions of the aliens and their actions didn't fill me with terror 
but there was enough action on their part to give me a growing sense of 
dread that the remaining humans would gradually be extinguished and this
 would be one of those stories where the aliens win. Eventually 
our characters meet but to say any more would spoil the story. I will 
say that when I got to the end, I wondered why he had a second and even 
third book but quickly realized so many questions hadn't been answered 
by the first book.
