This book was super captivating as it was a search for truth and freedom. Throughout the book, we see the struggles of people in a dying city; the lights are running out, and the food is too. Through these problems, we see the attempts people make to survive, which lead to people stealing food and hiding it for themselves. Luckily two brave kids choose to find the truth and go on a journey to escape the city. When they finally find the light they realize their whole lives they were underground in the dark. A whole world was waiting for them at the top, but because no one was brave enough, they were stuck in their dying city. This book teaches us the importance of curiosity and the importance of hope; without these, people would be left to die in a dying city, never getting the chance to see the light.
