She went to map his territory. He decided to map her. Elara Voss didn't fear the Serpentine Depths—she catalogued them. As Ironveil's only cartographer willing to cross the border, she expected danger, not captivity. Not him. Zyrith, the naga warlord who rules the coil, has kept humans out for decades. When one stumbles into his territory unafraid, he doesn't kill her. He keeps her. One accidental scratch. One drop of venom. And Elara's body begins to betray everything she thought she knew about what she wants. The Ichor-Fuse is meant to bond naga mates across lifetimes. It was never designed for a human. Now Elara can feel his hunger pressing against her mind, his scent making her cunt clench with need she refuses to name. Zyrith won't touch her—not until she asks. Not until she begs. And the longer she stays, the more she wants to. Book 1, The Ichor Descent, a five-book saga featuring a determined human cartographer, a possessive naga warlord, size difference, venom-induced arousal, pheromonal obsession, and a bond that will rewrite her biology forever. This book ends on a HFN with series-level continuation.
