While this book was a very quick read, I can't say it was an enjoyable one. I found a lot of the characters immature and overly focused on love and romance, and the writing a little awkward at times. I watched the first season of "The 100" when it first came out and haven't watched anything past that, so it was interesting to see what changes were made when adapting the book for the small screen, particularly in the characters that were added and removed. I have to say that I agree with the changes the show made, and while the TV series started off as very immature, as the book did, the TV series reached a level of desperation and maturity that the book simply never achieved. For one thing, there wasn't a sense of urgency in the book. While the teens still face obvious challenges of the earth, the book doesn't possess the elements you would expect of a castaway situation: power struggle, finding food and water (other than hunting), and the danger of the world around them. It takes the entire book for a character to actually die, and so the danger the kids are in never feels real. This book was a gift (or more accurately, a hand-me-down), and I'm unsure if I will read the next one. I definitely won't buy it, but if I for some reason end up owning it, I will give it a shot. Hopefully, the second book is better crafted.
