Rupert Starbright, separated from his guide and protector Dream Weaver, travels the dangerous Wildness with two wild boys who have vowed to help Murkus defeat Queen Chroma and conquer Far-Myst. Separated from the boy who calls himself Xerks, Rupert and the other boy, who is none other than Dream Weaver's son Quix, stumble on a gateway to a land of mystery—My-Myst, the land of the dreaded Truseens.

As Murkus, now a creature half man and half dragon, sucks all the joy and color from Far-Myst with his deadly dark sun, Rupert decides he must confront his enemy and ask him why he so hates imagination and its wonders because no one else is willing to do it.

Is there something good buried deep within the black heart of the Dragon Lord? And are Rupert's faith and imagination strong enough to find it and keep Far-Myst from becoming another Graysland?
