Lars, the little polar bear, is bored and hungry. He figures that the skies above the dump will be more interesting than the endless ocean. After assembling an al fresco lunch, he ambles over to the railroad siding to eat; there he encounters a young tiger, Sasha, a wayward train jumper who wants to go home. When the train begins to move, Lars becomes a train jumper, too. They head toward Sasha's home, through the boreal forest, across the high plains, and--it's assumed--to Siberia. Then Sasha's father, with Sasha on his back, takes Lars home. During that trip, Lars gains a new appreciation for his home. De Beer's pen-and-wash illustrations verily summon the landscapes traveled through, and there is the pleasurable curiosity of a tank car covered in Cyrillic writing. Not, perhaps, a geography lesson, but a pleasant tale of a friendly sojourn.
