That was an enveloping post-apocalyptic story! Well, actually a very good start of stories about a post-apocalyptic world in which people live inside a buried vertical cylindrical structure, called the silo. People inside the silo don't know exactly what happened to the world outside, they don't actually know a reality other than the structured life inside the silo. The biggest penalty for them is to leave the silo because the world outside has become quite deadly.
As the story develops itself through the eyes of the characters, we are confronted with many mysteries and questions unanswered, the same questions the characters make themselves. I loved the pace and the suspenseful aspect of the book, in which the author presents a situation, that you have no idea how it could have happened, and then goes on unraveling the story. It is that kind of story that keeps up up at night, kind of addictive. I was really afraid that towards the end (about 97%) I would face a huge cliffhanger. But no, it was okay, I had tears in my eyes by the end the book, feeling like a stage has been successfully completed, and every character is ready for the next step. The characters are captivating, the heroine Jules is awesome and I cared a lot about her and her friends and family. It was very easy to create a connection with them. The fact that not all the questions are answered or facts explained right away is, for me, the greatest force of the story. I think maybe the way the author structured the chapters encouraged me to always seek for more, and at the same time, it was okay to give the book a pause because the chapters were not too long. I really enjoyed that pace.
I definitely want to know more about this world and the future of the characters of the series!
