Malcolm's metaphysical adventure novel The Sun Singer tells the story of young Robert Adans who steps through a hidden portal deep in the moutains and discovers a mirror-image reality where time is on a different road and the magic is stronger.

When he could not prevent the death of his best friend’s sister (which he saw in advance), teenager Robert Adams turned away from his psychic abilities.

Now, with the death of his avatar grandfather on the eve of a family vacation to the western mountains, Robert continues a mission the old man only could only hint about during his final days. Robert hears the call to adventure and plunges into a world at war. After the chaos of the threshold twists his memory, Robert not only cannot tell friend from foe, he no longer knows who he is.

The journey is a physical one: mountain trails, a resistance group fighting a tyrannical king, a vision quest on a mountain peak. The inner journey is the one that matters, bringing back sanity-threatening talents and the kind of magic that will subdue enemy soldiers, heal the sick, and bend time itself. The Robert who returns, transformed into the Sun Singer, is not the Robert who walked into the mountains as a fairly typical young man.
