Berta is tidy, never throws tantrums, and never cries. Whenever she feels overwhelmed, she just opens one of her boxes of emotions and shuts in her tears, fear, and anger. But what would happen if one day she lost control? Berta discovers that emotions should be felt and not locked up. Berta’s Boxes is a wonderful story about dealing with emotions and learning to understand and express your feelings.

A Berta le gusta tener todo ordenado, incluso sus emociones. Si un día siente rabia o demasiada tristeza, abre sus cajas de colores y mete las emociones dentro. Pero un día Berta pierde el control… Porque, ¿podemos encerrar las emociones en cajas?
