What would you do if you lost everything to something which you didn’t know existed until just a few months ago? Cassie Sullivan goes through all of this in The Fifth Wave by Rick Yancey. In Ohio, the invasion of the “Others” has hit hard. People have been kidnapped, brainwashed, even just flat-out murdered. Cassie’s brother, Sam, was kidnapped by the Others months ago, and has been trying to save him since. After being shot by a soldier for the Others known as a "silencer” she is saved by a mysterious guy named Evan, and he helps Cassie get to Sam. The two of them find the camp where Sam is being held, and from there it’s a fierce battle liberating him from the brainwashing site. This book is an absolutely amazing, action packed adventure, and I’d have to recommend this to people who like books like The Maze Runner, as it is about a dystopian society and has the same sci-fi elements. Quick content warning though, this book should definitely be read by 7th grade and up, as there is very frequent violent content.
