Valley of Sylveren #3
Mistral Hearts
Not yet published
Expected 5 Mar 26A diviner who’s sworn off romance. An heiress who’s all business. Fate brings them together, but the fear of love could drive them apart.
Calya Helm is determined to take over her family’s shipping company and lead it to greatness. Nothing will stand in her way. Not the stuffy trustee appointed by her doubting father, her shady ex-business partner out to fix his tarnished reputation, or even the smidgen of guilt she feels for unintentionally disrupting a Sentinel’s mission.
Nocren Lowe is a Sentinel of the Valley with a gift for divining using the wind. Haunted by the risks of his magic and the pain of past betrayals, he’s convinced there’s no room in a diviner’s life for romance. He’s content to do his work as a ranger and avoid forming serious attachments, even if the wind keeps whispering about the importance of a certain ambitious young woman.
When Calya’s probe into suspicious company documents aligns with the Sentinels’ investigation into a group of elusive mages, she strikes a deal for them to travel together. In the confines of a small ship, the mutual attraction she feels with the brooding ranger burns hot, and they agree to a single tryst. No sentiment allowed, and once the voyage is over, they’ll go their separate ways.
But their arrival in town only leads to more questions as carefully kept secrets unravel. When an old foe rises with a scheme that threatens Calya’s homeland with a deadly blight, she must decide what—and who—she’s willing to risk.
Mistral Hearts is the final cozy fantasy romance novel in the Valley of Sylveren trilogy. If you love spicy reluctant allies-to-lovers, snarky banter, and adventure with a touch of mystery, get swept away in Mistral Hearts!

Mistral Hearts by Jaime Ryanne
(Final book in the Valley of Sylveren trilogy)
Mistral Hearts is the perfect farewell to the Valley of Sylveren—a cozy fantasy romance that delivers spice, adventure, snark-filled banter, and just the right touch of mystery. As the final installment in the trilogy, it feels both deeply satisfying and bittersweet.
This story belongs to Calya Helm, and what an absolute joy she is to read. Capable, tough, and yes—sometimes a little prickly—Calya is the kind of heroine who stands firm in her strength without losing her heart. Watching her walls slowly shift and soften made every page compelling. She feels real, layered, and fiercely herself.
And then there’s Ranger Nocren Lowe… who will be living rent free in my heart for the foreseeable future. From the outside, he’s reserved and standoffish—but for Calya? He is anything but. The tenderness beneath that controlled exterior made me swoon more than once. The line, “While Calya Helm might taste like a mistake, Nocren could not find a drop of regret,” absolutely wrecked me in the best way. Their reluctant allies-to-lovers dynamic is full of delicious tension, sharp banter, and slow-burning chemistry that pays off beautifully.
The plot is well developed, the pacing is spot on, and the character growth feels earned and organic. The world-building once again immerses you so completely that you feel as though you’re walking the Valley yourself, I swear I can feel the rain! But what truly made this book shine for me was the emotional core—the friendships, the family bonds, and the deep connections that thread through the story. Those moments hit hardest and are what elevate this from a great romance to a truly memorable one.
I’ve loved this entire series, and watching Jaime Ryanne’s writing grow stronger with each book has been such a pleasure. Saying goodbye to these characters is bittersweet—I’ve treasured being part of their journey.
I already can’t wait to see what she writes next. She has firmly secured her place as one of my go-to authors.
Thank you for having me as part of the Street Team and for the privilege of reading the e-ARC!

What a way to end the series! We discovered the cure, we found 'Villain' and Brint is still the dude I hate till the very end. It was such a heartwarming moment when the group witnessed the cure working against the poison.
Calya was such a strong character - she's fierce, she's determined, she's a risk taker. No one, not even her own Father could falter her from her morals. I love that the two sisters were so different from one another yet both held true to their own value and purpose.
Lowe was definitely a cinnamon roll in my eyes despite having been betrayed in the past. His unique wind magic was a cool concept and I loved that it bent to Calya.
I do wish there was more dialogue written in this book. At times I felt I was just reading paragraphs of descriptions or characters internal monologues. Just a preference! Thank you to Jaime for this ARC, I loved this world and am sad it's coming to an end.

This was a cozy fantasy love story wrapped in almost historical romance.
Cayla, our FMC, is back to reclaim Healm Naval Engineering, the family business, but is really hindered by the Coalition who want to control everyone and everything.
Brint, the MMC, is both a problem and a solution, but neither of them are great at trusting.
This is the kind of book where magic is a normal part of life and in the case of the Coalition, another way to control and make themselves more powerful & wealthy.
I wouldn’t call it an enemies to lovers, but there are some great fighting & making up scenes.
This is a SPICY book! Don’t get it twisted - but it’s also a book about trust and love & priorities.
This is book 3 in the world and I highly suggest reading the others first. They are great fun!
Thanks for the arc!
