A board book of concepts explained with images and a word for each one. All the word-images are related to black and white and follow a circular narrative thread through the images. On each double page there is an illustrated element that plays with these two colors, for example: the moon, a cobweb, a piano, a fridge, penguins, a zebra crossing, cows, the snow, a snowman, a Dalmatian, the night and thus up to 22 concepts. Meritxell Martí is an artist, a composer, a musician, an award-winning author of more than 30 books, and an art and literature professor.  She is the author of La isla de las 160 diferencias and Me llamo Mozart , as well as many other books.
