He is sworn to stop what she’s becoming.
Flora Domhnall is the last of her line—her clan’s only defence in a war between the Everfolk, where human lives are cheaply spent. When she finds a wounded immortal warrior bleeding in her woods, she has no choice but to save him. If he dies on her land, her people will pay the price.
What she doesn’t know is that the oaths carved into his skin will demand her death.
Chyr’s oaths bend his will and his life to a single purpose—one that will turn him against her the moment they awaken. But celestial iron is poisoning his body, and the war he was sent to win is slipping out of reach. He won’t survive without the mortal woman he should never trust.
Hunted by the enemy, bound together by necessity and a growing attraction, they cross moor and mountain while war burns through the Highlands. Every choice Flora makes draws them closer to each other—and draws the notice of the ancient gods. An ancient power wakes beneath the hills, the magic of the Cailleach Queens that has waited four hundred years for this moment and this woman.
A power Chyr’s oaths will force him to destroy, even against his will.
From the award-winning author of Compulsion and the Celtic Legends Collection, The Crown of Moonlight is perfect for fans of Juliet Marillier, Diana Gabaldon, and Rebecca Ross—or anyone who wants their hero broken open by a woman’s kindness.
“As a massive fan of Outlander, I went into this story hoping for a touch of sweeping romance, aching emotion, and lush world-building—and I was not disappointed…the same sense of fate-touched love, and that slow, simmering tension between two characters who feel destined for each other.” —Lilith’s Library
“I didn’t expect a Highland fantasy to feel this haunting and tender, but The Crown of Moonlight swept me away. Boone gives us Flora Domhnall, a courageous woman caught between loyalty to her clan and the dangerous pull of an immortal warrior…a slow-burn romance wrapped in rich history and magic.” —Librarian/Netgalley Review
“Boone’s prose feels both timeless and cinematic—windswept moors, crumbling castles, and an undercurrent of old-world magic that hums through every scene. The dual POV structure adds depth, letting readers feel both the mortal cost of Flora’s courage and the immortal ache of Chyr’s duty. Their chemistry is beautifully rendered—equal parts tenderness and turmoil—never rushed, always earned. Boone deftly weaves themes of honor, sacrifice, and destiny into a narrative that’s as romantic as it is epic.” —ARC Reviewer
