From publisher blurb:
MALAKAR, THE VOIDWALKER
In the dead of night, whispers tell of a monster that stalks the space between worlds. It is an ancient being made of the very fabric of the cosmos and the stuff of nightmares: Malakar the Voidwalker. He carries his dark tome, crafted from the void itself and imbuing him with power beyond measure. Its secrets have driven him to madness, and his mind is now a vortex of chaos and dark magic. Yet, he roams the stars, his power growing with every nightmare he conjures.
