The narrator, a young boy, sees his life transformed for the better when a family moves in the twin house next door. The son, Jacob will become his friend and from that first day, they won't pass a single day without seeing each other, talking, playing or leaving each other gifts or messages in the hollow of the tree. But one day, Jacob, unexpectedly, leaves. A beautiful story of the power of friendship and the emotions it brings. The main characters of this tale are two boys –the narrator and Jacob–, a place –a village placed between the sea and a hill–, and time. The time that belongs to the games, when each one realizes he has found a partner to share dreams, challenges, hopes and fears. And time to remember and to feel an unbearable longing, because one day Jacob’s family leaves without saying goodbye. What’s left for the person who is still there? The pain, the abandonment, as big as a mountain? A memory that allows you to hope? A surprise hidden in a secret place? A tale told like an elegy, a tale that flows like our own memories, illustrated in a realistic style, that also offers symbolic elements that invite the reader to contemplate the beauty of art and literature, and finally to think about the things that really matter in life.
