New Release | The Shadow Fixer

Greetings, All!

I’m thrilled to announce the release of the sixth book in the Division Zero series – The Shadow Fixer!

It’s available now on Kindle, coming soon on paperback.

Happy reading!


Kirsten Wren’s job has gone back to normal—ghosts are killing people again.

After twenty-three rough years, Fate seems to be giving her a break. Her adopted son is happy. The new—well, first—boyfriend is doing everything right… and she hasn’t seen a single demon in a few months. In 2419, West City is a violent place filled with poverty, overcrowding, and augmented cyber-gangs. No surprise vengeful spirits are everywhere.

Compared to creatures of the Abyss, however, angry ghosts are like old friends.

An unusual spike in hostile manifestations suggests something out there is stirring up spirits. Initially benign events rapidly become deadly. As the only Astral Sensitive the National Police Force has on the West Coast, Kirsten might be in over her head.

The incidents continue at an overwhelming pace. Responding to so many hauntings leaves little time to find the cause of the ghosts’ agitation, but if she doesn’t do something soon… the city will descend into spectral chaos.

New Release | The Queen of Discord

Available now on #Kindle – Book 4 in the Temporal Armistice Series – The Queen of Discord.


Brooklyn Amari exists to destroy the world—but she doesn’t want to.

It’s not every day a person finds out their father is an ancient demon, two powerful armies expect her to end creation, and everything people think about celestial beings is completely wrong. Such news would break most people. Fortunately, Brooklyn’s tough. She’s also kinda lazy, which works, since saving the world requires she do nothing at all.

Good chance her life has gone off the rails when giant lightning-spitting birds are the least of her problems. Her friend is in deadly trouble with a gang and the warmongers hatch a devious new plan to destroy the Armistice—a.k.a the world—without her.

Sitting on her ass ignoring everything won’t cut it anymore.

Worse, she can’t stop thinking about the eco-terrorist mage attacking industrial sites across the country. Chasing people down is totally not in her job description as a firefighter, but such a strong psychic fixation is a big red flag. If Brooklyn’s limp excuse for a conscience doesn’t wake up, something bad is going to happen… probably to a bunch of innocent people who don’t deserve it.

Daughter of Mars Sale

Grab the three-book cyberpunk espionage thriller series, Daughter of Mars for .99 each until Jan 31!


Humans have killed for land since the dawn of civilization, and in 2418, the fight has moved to Mars. Colonies formed by the two greatest governments of Earth compete for space on the red planet, where borders shift with every drop of blood. Amid this war rises the Pueri Verum Martis; a secretive resistance movement that rejects both governments and seeks to define Mars as a sovereign world.

Risa Black is a true daughter of Mars―a cybernetically augmented spy, assassin, and patriot wanted as well as feared by both sides. Many soldiers facing insurmountable odds ask help from higher powers.

In her case, however, the angel speaks back.
