Claimed by the Forest Gods. The Forest Gods Trilogy, #3

The forest is dying. The gods are unraveling. And Mira has become something more than mortal. After discovering the depth of the gods' love-and the truth behind the decay spreading through Arenwood-Mira follows a mysterious pull that leads her to a forgotten cavern and a prophecy carved into stone. One woman. Three gods. A Seed meant to restore the world. But restoration has a price. In a final sacred ritual, Mira and her antlered lovers must come together not just in body, but in spirit.
Under the full moon and the watching trees, they perform a union that will awaken ancient magic, test their bond, and change Mira forever. As golden light floods the glade and the forest begins to breathe again, Mira must face the truth of what she's become: a vessel of life, a goddess in her own right, and the only one who can carry the future of Arenwood. Claimed by the Forest Gods is a steamy, emotionally charged conclusion to the Forest Gods trilogy-featuring reverse harem romance, forest magic, divine intimacy, symbolic pregnancy, and one woman's transformation into a living legend.
