"So I can rejoice?" Little Jan doesn't really know why, but he feels that the fact that there are five of them at home is not very good news. Grandfather Joan and grandmother Caterina leave their native village to move in with them in an apartment in Barcelona's Sant Antoni district. This change disrupts the daily life of the household, where words and silence suddenly take on a new meaning. Jan and grandfather Joan, however, have their own world, full of walks, trees and letters that have a deeper meaning than it might seem at first glance.

While the adults try to keep everything going as usual, Jan notices the little things around him and gradually builds a picture of what is really happening. Conversations between grandfather and grandson, full of questions without answers and answers without questions, make up a mosaic of their relationship, which will be guided, among other things, by the story of the grandfather's willow tree. The Memory of a Tree is a novel that can put the reader in the role of a child. It tells about the passing of memories and how they are created and preserved, where they are stored and how they can be lost.
