This illustration shows how imagination paired with passion helps eliminate barriers and boundaries. The ceiling breaks through to give space to a vast universe, and you forget everything while flying lightly in your dreams. The protagonists are twins who, bound by a great interest in the cosmos, imagine what it might be like to live in space floating among the stars and planets.

I set the scene in a dark living room, like the one where I used to read stories and descriptions of distant and fascinating worlds, planets where it rains molten glass, and stars thousands of times bigger than our sun. How not to be fascinated by such curiosities?
