Little Bo is afraid of the dark. When the other troll children run out into the night to play, he doesn’t dare to follow them. One day at sunrise his best friend Glowy doesn’t return to the cave. If trolls are outside when the sun shines they turn into stone! But even though the sun is about to rise above the distant mountains, Bo runs out to rescue his friend. . . .
