Martina se une al equipo de fútbol de su colegio con mucha ilusión. Es muy buena defensa y está dispuesta a dar lo mejor de sí misma. Pero después del primer partido, empieza a notar que el capitán quiere destacar y no juega en equipo, y los jugadores no la consideran una igual por ser una niña.
Martina creará otro equipo de fútbol más igualitario y diverso, donde jugarán y competirán sin olvidar divertirse.
De la mano de Susanna Isern, autora de Daniela Pirata (más de 180.000 lectores) y Marta Moreno, ilustradora de El hilo Invisible (más de 150.000 lectores).

Susanna Isern grew up among mountains in the Spanish Pyrenees. When she was little, her favorite hobby was to run around, discovering incredible insects and helping sick or endangered animals. It was then that animals started to whisper her stories, which she hurried to write in the notebook she always carried with her. She is the author of many children's books, most of them distributed internationally and translated into over a dozen languages. She has been awarded the Silver Medal in the Moonbeam Children's Book Awards 2013 in the USA.

Marta Moreno was born in Barcelona (Spain) and studied Illustration at l'Escola D'Art de Tarragona. She currently combines her work as an author and illustrator with teaching in small rural schools and her pupils are a great source of inspiration for her.
She has published more than twenty books, some of which have been translated into numerous languages.
