The characters from The Lonely Mailman and A Mystery in the Forest return in a story about bullying and the importance of speaking up when it happens around us.

A little beaver with droopy ears and a sad expression.

A mischievous boar.

And a squirrel who doesn't miss a thing.

Little Beaver always went unnoticed. At school, he always sat in the back of the classroom; in the forest, he would hide behind the trees so that no one would spot him. However, although he would have wished to be invisible, misfortune and setbacks haunted him. Little Beaver seemed like bad luck's shadow. But... Why did everything happen to him? One day Squirrel realized that coincidence was not the reason for Beaver's sad eyes. Willing to discover who is behind these small injustices, Squirrel will seek the help of all her friends to awaken the voice of the forest, that voice that always brings peace and unity.

Daniel Montero Galán (Madrid, 1981) was born prematurely, at the early age of zero. His head was always full of birds. As time went by, they reproduced, and along came a lot of different kinds of creatures, making a great noise--squawks, grunts, and screams... so he decided to transfer them into a paper to silence them. He keeps a deal with his drawings: they live thanks to him and he lives from them. Because of this symbiosis, more than thirty illustrated books stand up for him to testify that his thing in life is drawing. Day by day, and every other night, he continues to perfect spiral and rectilinear shapes to keep fit without losing shape. Watercolor fights a great battle with the marker to have a leading role on its cardboard.
