A tale of blood and elder magic, where the air flays the mind of its memories, and the trees bleed psychotropic venom. A wanderer scours a sentient forest of flesh and delirium for the only thing that he can still remember: his daughter, exiled from time when a devastating cataclysm doomed the world to an eternity of suffering. The Astral Wanderer and the Forest of Tears is the first book in a series of three, fusing the genres of cosmic horror, dark fantasy, and apocalyptic science fiction with the surreal dread of a twisted fever dream. This book contains scenes of violence that may be unsuitable for some readers.

In the second book of the Astral Wanderer series, the dread Wanderer screams across a sea of cancerous flesh in a craft of unbridled speed and destruction, bound for the heart of the undying forest, and the daughter he forsook in ages past. On his journey, he must contend with incarnations of his terrifying past; pirates who have abandoned their souls to the ceaseless hunger; the whispers of insanity that claw at his mind; and a star-maddened captain hunting him to the eye of creation itself.

In the second book of the Sister Verse, Diana and her party must brave the surreal and violent wastes of the Dreadlands once again in their quest to recover the Devouring Glass. With the aid of a mysterious wanderer who can bridge the void between worlds, they must infiltrate the darkling capital of Lao-Va, and come to terms with the truth of their world, or be damned to a fate worse than death. This book contains scenes of violence that may be unsuitable for some readers.

In the third book of the Sister Verse, Diana and her party must journey to the forgotten wasteland of the fallen lobe, and recover the mythical Crown of Eyes, and with it, her memories. Meanwhile, the allied nations march upon Lao-Va, and Singer must lead a daring expedition into the writhing Elder World before all of creation falls to the darkling scourge. This book contains scenes of violence that may be unsuitable for some readers.
