I finished reading 'The 5th Wave' last week and, although I have already talked about it a little on a video, I thought a full review might be more helpful for some people.
The 5th Wave is written by Rick Yancey and it's classified as young adult science fiction, but most of the plot is centered in a post apocalyptic setting.
If you go on Wikipedia, Goodreads, or anywhere else, they spoil half the book in the synopsis. I think it's better to find out for yourself and have that element of surprise.
Without giving anything away, all you need to know is the following. Not many people are left on Earth because of these waves that have been going on. You will get to know what, how, and why, don't worry about it for now.
Cassie is the main character, a girl fighting for survivial, not trusting her environment due to everything she's experienced since this whole thing started. You will like her.
The novel follows a few different characters, and some chapters are written from their perspective. If you're not a fan of this, neither am I, but it really works here and it does serve a purpose. It is a young adult novel, so all the main characters are young, kids you could even say. They're not annoying teenagers, though, they've been through a lot and show a lot of maturity.
I loved this novel so much I'm currently reading the second part, The Infinite Sea, and I don't tend to read trilogies all at once. The science fiction elements are great as well, and I appreciate them very much.
The writing style is very easy to follow and the only thing I didn't like was the inclusion os a few pop culture references. It is funny or relevant now, but if you want to read this in a few years, it will feel dated and boring, or you won't even know what they're talking about.
There will be a movie coming out early 2016 but I wouldn't wait for that. If this seems like something you might like, read it. As it usually happens, books are better than their movie adaptations, so go ahead and have the option to make your own comments on that.
