Odd and the Frost Giants (English, Paperback, Neil Gaiman)

The winter isn’t ending. Nobody knows why.
And Odd has run away from home, even though he can barely walk and has to use a crutch.
Out in the forest he encounters a bear, a fox, and an eagle – three creatures with a strange story to tell.
Now Odd is faced with a stranger journey than he had ever imagined.
A journey to save Asgard, City of the Norse Gods, from the Frost Giants who have invaded it.
It’s going to take a very special kind of boy to defeat the most dangerous of all the Frost Giants and rescue the mighty Gods. Someone cheerful and infuriating and clever.
Someone just like Odd…
