Illustrated fantasy adventure set within the D’haran Empire, featuring the wizard Richard Rahl and young Kahlan Amnell amid a looming plague.

Young Gom Gobblechuck knows he's different from his brothers and sisters, and from all of the folk in the village. He is quick and smart, he looks like his mother rather than his father, and he wears a rune that his mother left him when he disappeared the night Gom was born. And Gom can talk to animals and to the wind. They are his friends, more so than the village children, who think him strange. Gom's father is a woodcutter, and everyone expects Gom to follow in his father's footsteps. But Gom is sure that his destiny lies elsewhere. Why else would he have such gifts and talents? An evil man comes to the little village of Clack, and Gom leads him on a dangerous chase into the very depths of the mountain. Amidst pitch-black tunnels, caverns, and endless abysses, Gom must loose his mad pursuer or perish in the bowels of darkness. Will he ever live to see daylight and begin his quest for his mother?
