Little Adam can suddenly hear what the trees tell each other across the continents. It happens on his visit to California with his dad. Full of excitement he hears how many-thousand-years-old sequoias talk to each other and he can listen to stories told by trees all over the world: the Wollemi pines in Australia, the downy birch in Iceland, Old Tjikko in Sweden, the Areca palm in Iraq, the fig tree in Italy, the linden tree in Czechia. The stories told by the trees take the boy back to the Indians, the Vikings and deeper into history, back to the dinosaurs and even to the creation of the world, to Adam and Eve.

When he returns home from the trip, he takes with him the decision to protect his wooden friends for the rest of his life.

And this is what the author recommends to readers at the very beginning of the book:

When the trees begin to speak, read very, very slowly.

Feel free to skip some pages so that you learn what you want— as if you were jumping from branch to branch.

Or climb up into the treetop and only read what lifts you up.

You can also let yourself go all the way down to the roots and wander around in their labyrinth.

Or climb into the tree trunk and just stay there.

After finishing reading this book, you will be a little different. You will no longer be able to walk blithely past trees. Sometimes you will want to stroke them, lean against them, hug them, climb them or simply lie under them for a while. You will defend them when they are about to be felled. You will feel that they are your brothers and sisters. And they are.
