The legend of the dream giants

Summary: "For many years, Berg has lived alone; the only reminders of his family are his mother's satchel and his recurring dreams of a white bear who shares a magical sand from a fallen star. Sometimes, when Berg feels lonely, he will risk entering a village to trade a smooth river rock or a feather for food. He's really searching for kindness and companionship; but with every attempt he makes, people chase him away, thinking he is Ünhold—a giant and a monster. In his travels, Berg comes upon a city made of iron, where he meets a little girl, Anya. To his amazement and delight, Anya knows about the magical dream-sand, too, and says she wants to be his friend. The mayor also befriends Berg and enlists him to guard the city from the dangerous Ünhold. But Anya suspects the mayor has other plans for the young giant. Fearing the city isn't safe, she warns Berg to flee. Confused and torn between his two friends, the young giant has to figure out where he can place his trust." -- goodreads.com
