Reading Order

Book 1 – Thunder & Flame

Five thousand years of duty. One night that changes everything.

The Elder Gods are stirring. Their prison is weakening. And the first seal has already been stolen.

In the remote wilds of Tunguska, Siberia, an archaeological dig meant to rewrite ancient history instead unleashes a cosmic horror. When Dr. Malinda Alexander uncovers a crystalline shard hidden beneath the ruin, she becomes host to Xal’thar, a being from beyond time. The brilliant scientist who once sought truth is transformed into a rising dark sorceress determined to free the Elder Gods from their dimensional prison.

Years later and half a world away in New York City, Eric Morgan—a 5,000-year-old immortal guardian sworn to defend humanity—rescues Mae Laveau, a Vodun priestess, from a necromancer and his shadow creatures. Their fateful encounter exposes a terrifying reality: Dark forces are moving, and the ancient seals safeguarding the world are no longer secure.
Seeking answers, Eric consults Lilith, immortal sorceress and Queen of the Night. She traces the necromancer’s power to a cult devoted to the Elder Gods and points Eric and Mae toward the location of one of the seals.

But they arrive too late. The seal is gone—stolen after a brutal mass murder carried out by Aztec-worshipping cartel cultists.

As Eric and Mae follow the trail of destruction, they uncover a continent-spanning conspiracy. From a supernatural speakeasy hidden beneath Manhattan to the devastated halls of the Los Angeles Museum of Natural History, every clue pushes them closer to Mexico City’s underworld, where the stolen seal fuels a rising storm of dark magic.

Along the way, they face undead abominations, Faerie lords, dragons, ancient immortals, and cartel sorcerers willing to sacrifice anything to awaken an Aztec god. Mae’s emerging magic grows stronger with every encounter, stirring forgotten memories and a destiny entwined with Eric’s across lifetimes. Eric must confront the echo of an eternal bond while racing to stop Malinda before she unleashes forces capable of ending the world.

The battle lines are drawn.
The seals are cracking.
And the war between light and darkness has only just begun.


Epic, myth-rich, and adrenaline-charged, Thunder & Flame launches The Eternal Sentinel Chronicles—a sweeping saga where modern cities hide ancient powers, cosmic horrors rise from forgotten tombs, and an immortal warrior confronts enemies older than civilization itself.

Book 2 – The Daughter of the Night

She arrived bleeding, unconscious, and carrying a secret five thousand years in the making.

The woman Eric Morgan never knew existed -- his daughter, Siobhan, born of Lilith and hidden from the world for over two centuries -- nearly died getting to him. She had moved alone against the Mistress, trying to stop her from obtaining a second seal on the Elder Gods' prison. The modernized Nachtsturm trooper that nearly killed her was proof of something terrifying: the Mistress wasn't regrouping after Mexico City. She was already a step ahead.

Now Eric, Mae, and Siobhan are racing across two continents -- through Faerie Roads, Parisian sanctums, and frozen Bavarian vaults -- hunting the same enemy that hunted her. The Mistress is building something. Nachtsturm war machines. A revenant Nazi scientist. An army designed with one target in mind.

The Godslayer.

The conspiracy didn't end in Mexico City. It was just getting started.

Book 3 – Shadows Rising

Two worlds at war. The shadow invasion begins.

Supernatural chaos erupts across the globe -- coordinated strikes designed to overwhelm humanity's defenders and mask something far worse. Over 200 dead in a single night in a quiet West Virginia mining town that most maps have forgotten.

Mae Laveau and the immortal Siobhan must contain a nightmare that grows stronger by the hour. They're on their own.

Eric Morgan and Lilith are trapped in the Shadow Realm -- where they've discovered a threat even greater than the Mistress's schemes. A vast invasion force preparing to breach the barrier between worlds.

Two wars. Two realms. No margin for error.
