The Crown of Moonlight

An epic slow-burn romantic fantasy rooted in Celtic fae mythology—perfect for readers who love strong, determined heroines, wounded heroes, Highland rebellion, and enemies forced into dangerous loyalty.

Five crowns. Two reluctant lovers. One throne between them.

Flora Domhnall is determined to protect her people and keep her Highland clan neutral in a war between immortals. Then she finds a dying warrior—one of the rebel king’s Riders—bleeding in her woods. If the Raven Queen’s soldiers catch him, Flora’s clan will hang as traitors. If she turns him away, the rebels will demand revenge.

Chyr never expected to owe his life to a mortal woman. He’s supposed to be immortal, but a mysterious wound is dragging him toward death, and the doorway back to his world is sealing shut. If he misses it, the queen will tighten her grip on Flora’s realm and turn her conquest toward Chyr’s world beyond the veil.

Bound by necessity and hunted at every turn, Flora and Chyr cross moor and mountain while the Highlands burn and the ancient land awakens in fury. Flora’s magic defies the oaths that bind Chyr, but as her power grows, he needs her to wield it. To save his people and hers, he’ll pay the price in pain and heartbreak.

Honor is everything—until it isn’t. Then you hunt for the one chance left.

What Readers Say

"T𝘩𝘦 𝘊𝘳𝘰𝘸𝘯 𝘰𝘧 𝘔𝘰𝘰𝘯𝘭𝘪𝘨𝘩𝘵 is one of the best books I've read this year! Set in a Celtic fantasy world inspired by Scottish history, this epic fantasy romance is absolutely amazing. Martina Boone's descriptions of the hauntingly beautiful highlands are lyrical and vivid…Flora is such an inspiring main character: resilient, wise, courageous. I love her deep connection to animals, the land, and the elements, as well as her kind heart."

— Forest Crone Books

"“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. In fact, the similarities were uncanny in the best possible way. There’s the same richness of setting, the same sense of fate-touched love, and that slow, simmering tension between two characters who feel destined for each other, even as the world threatens to pull them apart.”"

— Lilith's Library

"“You can’t help but admire these two great main characters. They both have all the qualities I would wish for in a strong story line like this. Compassionate, strong, fierce and loyal with a deep connection to each other that matters, but they also have plenty of conflicted emotions and loyalties that may not align that they both must navigate. The depth of writing makes these characters feel like they will jump right off the page at you.”"

— Maui Reader

"Every scene felt cinematic, wrapped in moonlight and mystery. The romance is gorgeously written — slow-burn, emotionally layered, and incredibly satisfying. The characters are real, raw, and beautifully flawed. Their journey is not just one of love, but of healing, trust, and transformation. "

— ARC Reader Dayna

"“This book was such a breath of fresh air. I fell in love with the world and the main characters, Flora and Chyr, within the first two chapters. Chyr is the perfect mix of morally gray and golden retriever energy—with plenty of “touch her and die” vibes! Meanwhile, Flora is a strong yet soft FMC, learning her magic and its power as she goes…they’re just meant for each other, and it’s beautiful. I was squealing and kicking my feet the entire time! I’ll be thinking about Flora, Chyr, and this magical world for a long time to come.”"

— Hannah Dreams Books

"“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. Fans of A Court of Thorns and Roses, Outlander, or The Cruel Prince will feel right at home—but Five Crowns stands proudly on its own.” "

— ARC Reader Lisa

"“I immediately started getting lost in this book, and it was a struggle to force myself to stop when I needed to. Right from the very beginning this story was able to grab my attention in a way I haven't felt since 2023 and…introduced me to a world I didn't even realize I needed. I'll forever be grateful and a loyal fan of The Five Crowns series as it begins its journey!”"

— ARC Reader Tash

"I haven't read a book that I can confidently rate 5 stars in a bit! I got to get my hands on a copy of Crown of Moonlight as an ARC and I loved every second of it! "

— ARC Reader Shelby

"If you love star-crossed romance and heroines who deserve their power, you'll love TCoM ♥"

— ARC Reader Nora

"“This book was so much more than I expected in all the right ways. It tore my heart apart and stitched it back together too many times to count. The Crown of Moonlight covers grief, love, lust, hope, rage, morals, values, ethics, and everything in between. There were two scenes in this book that had me put the book down and stare off into the abyss and even though it’s usually caused by heartbreak I love when a book makes me do that.”"

— ARC Reader Samantha

"“I just finished reading The Crown of Moonlight, and wow... The story is beautifully revealed but it's the chemistry between Flora and Chyr that kept me engaged. She is a fragile human, but her heart is mighty, even when her self-doubt and fear keep her on pins and needles. Chyr admires her strength, as any intelligent man should, and protects her well-being and choices even when he realizes her destiny is a dangerous one. The slow burn romance is very well-executed, and the plot twist at the end is a cliffhanger moment.”"

— ARC Reader Sumi

"“I gobbled this up! The Celtic back drop allows for a unique feel to the ever popular romantacy genre. This was an immersive experience due to the wonderful world building, awesome character development, and a magic system that is easy to understand and feels unique.”"
