The main main characters in the 5th wave are Cassie Sullivan her brother Sammy, Ben Parish, and Evan Walker. The main story goes like this. One day an alien ship appears in the sky, these aliens are called Others, and they start to to take over the planet. They do this in a very specific way, they do it by waves. The waves consist of different things. The first wave was a massive EMP strike which took out all of there power, even knocked planes out of the sky. The second wave was in fact a huge wave. The Others did this by dropping a huge rod from the sky which created an earth quake and in turn making a tsunami. The third wave was a plague, which killed most of the population. The forth was what the characters called silencers. Aliens in human bodies that came down to earth and were like assassins, they used sniper rifles to pick off anyone they saw. And the Fifth wave, which the book is about, you will have to find out yourself by reading the book if you haven't already. The main plot of the story is Cassie trying to stay alive and saving her brother.
A major theme that I saw in the 5th wave would be persistence. The main reason I thought of this would be because of the main character Cassie. When saving her brother she tried countless attempts to not just stop him from being taken but getting him back from who took him.
