About the Guardians of Light Series

Enter a universe where creation myths collide with cosmic rebellion, and only love can rekindle the light. In The Guardians of Light series, five legendary souls—gods reborn as angelic hosts—must rise against a false creator to restore harmony to the universe.

At the heart of it all are Incaendiel and Sophie, celestial warriors and twin flame souls torn apart by time and divine design. Together, they carry the power to redeem the fallen and rewrite fate. But their love is more than destiny—it’s the spark that could reignite the heavens.
Their children—Luxina, Damian, and Xavier—bear the burden of prophecy as the next generation of The Shining Ones, godborn heirs caught between angelic bloodlines and powers no one understands. As the apocalypse looms, they must uncover ancient truths, survive celestial trials, and face monsters born of a god’s corrupted will.

Alpha, the self-proclaimed god of creation, is no gracious god—he is the Demiurge, the architect of a false reality, the warden of the cosmos, and he will stop at nothing to maintain his illusion of order—shaping reality through fear and domination. He has created a universe where light is shackled, and truth is buried, and his consort, who once stood at his side—known as Omega and later Lilith—wants nothing more than to dethrone him using any means as necessary. The Shining One’s return threatens to unravel his design, awakening a power he believed long ago extinguished.

From the ruins of Atlantis to the Valley of the Shadow of Death, the Guardians of Light must gather allies—Nephilim, Fae, Werewolves, Vampires, and all Children of the Night, as well as their angelic allies—in a last stand for cosmic freedom. This is not just a battle between good and evil. It’s a war between truth and illusion, love and control, creation and rebirth.

For fans of Supernatural. The Mortal Instruments, Narnia, and Fallen, this mythic YA fantasy delves deep into Christian mysticism, cosmic memory, and the slow, painful beauty of becoming whole.

This series spans multiple generations, combining dark romantasy, angelic mythology, and epic twin flame/fated mates romance. Books 1-5 are YA and book 6 transitions to NA

Firefly of Immortality (Book 1)

Alpha and Omega are the rulers of the Universe, overseeing their angels and humankind. However, a battle for power ensues and half of the angels fall to balance the natural order of the cosmos, putting into motion the game of chess that Alpha and Omega, now going by Lilith, control. War has broken out between the angels as they fight to appease their creator parents.

Mortal-born angel Sophie is the key to winning the war. The side she chooses is the side that wins. The only problem… she doesn’t remember anything each time she incarnates on Earth. Her twin flame, Incaendiel, tries over and over throughout the years to get her to remember their bond of love before Alpha’s army wins her over. The time has come for her to get her memories back, but are they memories Incaendiel wants to truly know about?

The Apocalypse is on the horizon, and it’s a test of loyalty as to who stays with Alpha and who joins ranks with Lilith as they each make a power grab for the throne.

The Shining Ones (Book 2)

It’s been 8 years since Incaendiel and Sophie helped all of the fallen angels return to the summit. Both of them hold a secret the other does not know, and they have yet to see each other after Incaendiel has been stranded on earth to walk alone in darkness. But this isn’t about them, it’s about Luxina, Xavier, and Damien as they all stand the test of time against the fallen demiurge, Alpha. The clock is clicking closer to an apocalypse, and it is up to these three to stop it with their mysterious powers granted to them.

Firefly: The Half-Blood Angel (Book 3)

Alpha is getting closer to perfecting his experiments. His main test subject, Damian, is losing hope in ever winning the war against time. As Alpha creates more creatures, Damian is trying to stay alive. No matter how he tries, he can no longer please his master. His only option is to escape, but in doing so, he may lose the very thing he wishes to never lose if he doesn’t help other prisoners escape as well: Luxina. The clock is ticking closer to doomsday, and Damian is trying everything in his power to stop Alpha from bringing about the apocalypse.

The Valley of the Shadow of Death: Nephilim Rising (Book 4)

The Shining Ones have finally all joined forces against the tyrannical Alpha as the apocalypse looms closer and closer on the horizon. Alpha is creating more and more monsters and creatures daily to thwart the Guardians of Light in their crusade to restore balance. They are now on a quest to find the manna from the heavens to remove their Seelie enchantments and become the unrestricted beings the universe had intended them to be. Join Luxina, Xavier, and Damian as they face new monsters of the deep as they travel to the infamous city of Atlantis and come to terms with what the future holds!

Firefly of Immortality II (Book 5)

Back to the beginning—where eternity fractured.

In the long-awaited continuation of Guardians of Light, Incaendiel’s story finally unfolds. While the young Shining Ones faced trials of their own, he was trapped—his memories fractured by Alpha, his destiny twisted by Lilith’s cunning hand. But forgotten truth has a gravity all its own.

From the shadowed sanctums of Stygia to the luminous battlegrounds of Lightshade, Incaendiel must untangle layers of implanted lies, uncover ancient Gnostic secrets, and awaken the divine spark within. As echoes of the Fall resound across the cosmos, and Alpha’s apocalyptic design nears its crescendo, he finds unlikely allies—and one soul who may yet awaken his own.

But can love rise from the ashes of divine war? And will truth set him free—or destroy what’s left of him?

Ashes of Immortality: Black Wings of Death (Book 6)

Some truths do not set you free. They follow you.

As Luxina remains trapped within the lust terrace of purgatory—caught in a cycle designed to blur desire and choice—Damian is forced to descend elsewhere. From the depths of Sheol to the shifting corridors of Hell, the Guardians search for answers that were never meant to be uncovered.

With every step downward, Damian becomes more aware of what has always lingered at his back. Death has been watching him far longer than he realized, and time itself is beginning to bend in response to him.

Old alliances fracture under interrogation. Ancient evils stir. And the power pressing in on Damian feels less like survival and more like inevitability. The deeper they go, the heavier the silence becomes, and the harder it is to tell where justice ends and annihilation begins.

Some wings are born in shadow. Others are shaped by what waits below.
