Book 5
A Mature-rated dark fantasy tale for Seven Seas’ Ghost Ship imprint.

Deep in the tunnels of an abandoned mine lurks a demon that absorbs the power of anything it touches: the Black Ooze. When it consumes its first human male, it acquires both intelligence and ravenous sexual desire, much to the distress of a sorceress who mistakenly enters its domain. The heroes who seek glory and riches in these caverns are about to learn why monsters should be feared!
Book 4
A CITY IN RUINS.

Our heroines think they have dealt with The Black Ooze once and for all, reducing it to ashes deep within the lascivious cave where it dwells. But the Ooze is smarter than it seems, sending tendrils below the kingdom’s sewers, feasting—and growing stronger and larger—on bodily fluids and waste, quietly biding its time for the perfect opportunity to strike.

That time is now. Caught unawares, our heroines fall and the city now lies in ruins. The last line of defense is Queen Letitia, who just might be powerful enough to repel The Black Ooze. But will her hubris cost her her kingdom?
Book 3
AN INSATIABLE HORROR GROWS…

Fiana and Arfila, Knights of the Queen’s Guard, barely escaped from the slime caverns with their sanity. Regrouping at the palace, they are determined to return to the caverns and slaughter every last one of the slimes who violated their allies. But townspeople have begun to go missing in the night. A new nightmare is being born. The Black Ooze’s reach is spreading beyond the confines of the mine, spelling doom for the Kingdom of Fontilles and its citizens.
Book 2
FROM SEDUCTION TO SUBMISSION!

Consuming adventurers and bending female mages to its will, the Black Ooze grows in both power and hunger. Frederica and Satia, warped by demonic lust, hatch a plan to lure fresh bodies into the mines—and they’re on the verge of success! Is there any hope of escape for Fiana and the other victims?!
