Mac Barnett, Jon Klassen - Uma Aventura Debaixo da Terra

On Monday, Manel and João dug a hole. They had a mission: to find something spectacular!

Before long, the hole was deeper than they were tall. They kept digging—downward, then to the left, then to the right. They took breaks, had a snack, split up, and found each other again. But still, no spectacular thing. Until suddenly… they began to fall. And fall… An adventure through the multiverse with two brothers, on one of those nothing-special days that turn out to be simply unforgettable.
