I was having a nice argument on a Sunday evening with my brother, and when I finally went to bed sulking, I discovered that someone was wandering around our room, the door wouldn't open, the light wouldn't turn on, and an unknown boy announced to us in the dark that he had come for us to become siblings and take us with him to secret cities! Me and my trouble. My brother Elias. I shuddered at the thought of yet another brother sharing the same room, spreading chaos, but the situation seemed like a prank orchestrated by our parents, so we decided to follow him. Only it wasn't a prank. It was the beginning of an adventure that hid threatening bats that chew letters, dark wells, magical whistles, dangerous creatures called woodworms, secret cities, and a series of questions that demanded answers: Where are books written? Where are they stored? How are they preserved in our memory? Where does Page Town begin and where does Pencil Land end? How do you protect your favorite book and what is its value? How do you find your room again in a dark forest? When you don't know exactly where you're going, should you continue or turn back? If out of the blue you have to answer all of the above, it's better to hold your brother's hand tightly!
