This book is a milestone in Basque children's literature. The first edition was published in 1984.
Under the cloak of transparent writing and easy reading, with playful and timid illustration, Mariasun Landa offers us an unusual description of the children's world. she recounts that children may, as rarely as they do, have problems, without drama, without forcing the situation, but with enough realism for the reader to know what she is talking about. So we have the opportunity to meet a child who suffers from loneliness and lack of affection, Karmentxu, the only friend of Txan the Ghost.
