I was reading this to my 14-year old son, until he declared it 'lame' and we switched to a different book. I like it, so on 11/26/15, I started it where we left off, 13% in. 
 All done now, and so very glad I decided to keep reading it on my own! I picked this one out since my son and I read The Monstrumologist series, and I found Yancey to be an engaging writer. I liked this better than anything of his I've read yet; he really knows how to tell a story and hook you into his characters. 
 Cassie feels like she is the sole survivor from four devastating alien invasion waves that killed billions of people. She's scared, but can be fearless when it comes to sticking to her goal. Her sharp wit and general bad-assedness quickly pulled me in. 
 Yet Cassie isn't the only one left, and we slowly learn, through chapters presenting changing points of view, what the 5th Wave is. I see that some were confused by the multiple viewpoints; I thought it lent more intrigue to the experience. 
 While I could kind of tell where things were headed, it only made me want to read more quickly to find out if I was right. The ending felt satisfying, and I eagerly await my library hold on the second in the series to arrive. Read this book!!
