Stairway to Heaven

Corporal Jack Graven should be dead. Murdered by a vengeful angel at his own father's funeral, Jack is resurrected and returns to life carrying a terrible secret: he is the Archangel Gabriel reincarnated.
Jack's not the only one with secrets. His older brother, Lieutenant Colonel Tyler Graven "Demon of Kyoto", has just inherited his father's fortune and legacy as Lord of War, with no intention of stopping there: Tyler will someday rule the world.
The brothers reunite their elite military unit, "The Four Horsemen," with Tyler's longtime flame Colonel Diana Levitas and the mysterious Lance Corporal Jin Xialong. Together they seek to uncover the truth of Jack's past life and propel Tyler to his impossible destiny.
Thrust into a supernatural war, the Gravens find salvation through the Black Muramasa, a cursed black katana and the only weapon that can destroy immortals. As they uncover more mysteries behind the ancient blade, they come face to face with the Devil himself, but in the most familiar of faces. Their pasts, presents, and futures all linked, the Four Horsemen must end the war once and for all to survive with their souls intact. Failing could mean the end of the world.
A follow up to the explosive first book in the Ballad of Fallen Angels series, "Sympathy for the Devil," Book 2 is an action-packed, gun-slinging adventure that packs the punch of a military thriller with high-stakes supernatural intrigue.
