The Mourning Flame. The Last Immortal, #45

The Mourning Flame continues the gothic fantasy saga Last Immortal, following Francis and Stevan as they enter the Valley of Sorrows-where grief itself becomes a living force. When an ancient vampire empire is threatened by Lord Varek, a resurrected tyrant who seeks to control the Mourning Flame, reality itself begins to fracture. The Flame can restore the dead, but only at a devastating cost: every resurrection demands a life elsewhere.
As war erupts between ghosts, Ashbound armies, and collapsing magic, Francis and Stevan are forced into a brutal confrontation with love, mortality, and the limits of power. As the final battle unfolds, Francis must sacrifice a portion of his immortal essence while Stevan refuses to let him face fate alone. Together, they perform a forbidden binding ritual that stabilizes the Mourning Flame-but changes them forever.
Varek is destroyed, the valley is healed, and the dead are finally allowed to rest. Yet peace is not without consequence. Francis is no longer untouchable. Weakened but more human than ever, he and Stevan return to Blackthorne Keep, where they learn that grief cannot be erased-only carried forward and transformed. As spring returns to the mountains, a mysterious spark from the Mourning Flame suggests that new forces are awakening beyond the horizon.
Love endures. Balance holds. But the immortal story is far from over.
