Description

Sage Weldman has finally found his place at Shifters Sanctuary, a haven that rejects the rigid, outdated hierarchies of the world. As an omega who dreams of building a traditional family, Sage is perfectly content with his pack—until he realizes his heart is tethered to his best friend, Dexter. But with their shared history and the complexities of being two omegas, Sage assumes a future together is nothing more than a fantasy. Everything shifts when Sergio, a wise and silver-tongued unicorn shaman, enters the fray. What begins as a quest for equilibrium within the pack quickly devolves into a whirlwind of emotional entanglements. Dexter has long been firm in his rejection of fatherhood, and Sergio believes his best days are deep in his past, leaving Sage caught between the dreams he harbors and the reality of the three men standing at life's threshold. When fate weaves their destinies together, the trio must confront their deepest insecurities and the magic pulsing through their sanctuary. His Dragon Duo is a high-stakes, steamy MMM romance packed with supernatural charm, deep-seated chemistry, and the heart-warming promise that life’s biggest surprises—like sudden fatherhood—often arrive when we least expect them.

Delayed fated discovery

Sage, Dexter & Sergio I love Shifters Sanctuary. Their community is so wonderful and happily well run. The Alpha is a wonderful leader, and doesn't override the very knowledgeable betas and omegas in his pack, which is half the issue their entire extended society is having with designations anyway. I love the dragon brothers, and I'm so happy we've been given the chance to explore Sage's story. His relationship with Dexter was so fraught with drama in the past (that we didn't learn the details of until this book) but knowing even before this that they had been best friends told us there was definitely something hiding beneath that heartache. Bringing Sergio back into the fold to balance out the two omegas was a lot of fun. It's been so long since Brandt's book that I hadn't recalled the connection between Sergio & the two dragons, but I'm sure if I went back, I'd remember. His Dragon Duo was an incredible read although it definitely had its stressful points. I loved how strong each of the mates had to be for one another with the situations they found themselves in. The action and tension in this story kept me so engaged that I read it all in one sitting and I do not regret that at all. I received an authorized copy of this book and am volunteering my honest review.

An unexpected bond. 4.5 stars

4.5 stars The story of Dex and Sage and the fulfillment of what led to their breakup 100 years ago, all precipitated by the reemergence of Sergio, the unicorn beta with the Magic to unlock hidden alphas, was a series of right time, right place events with unexpected outcomes. Shifters Sanctuary is continuing to function well as a pack as Eric and Brandt carry on with their research into identifying potential alphas in betas and humans. Dex and Sage help with research while rebuilding their relationship and pining for each other through the attraction between them that is still there after all this time. Dex has had repercussions in his life over the last 100 years due to the choices he made, ones which he hasn’t shared with Sage, but with new developments, there is hope that may change. Unlocking Parties to help identify latent alpha designations continue, with illegal scent blockers at the parties becoming a more concerning problem for the pack as more and more surface at the events. The unexpected return of Sergio and his Magic starts a series of events with consequences for Dex, Sage, and Sergio as usual routines, expectations and designations are suddenly challenged overnight, and a new dynamic between them will change their lives forever. A lot is going on in the background, all to help support and hinder the new, and unexpected, relationship between Dex, Sage and Sergio, as their personal situation gets overshadowed by the need for Sergio to help the packs in Europe…

An MM, Fated Mates, Second Chance Romance

I love all of Anna’s books, and this one was no different. It was the perfect blend of fluff, spice, emotion, and suspense + omv, dragons, unicorns, and mpreg; what’s not to love? I was instantly intrigued when I met Dex in previous books, and his relationship with Sage has been a roller coaster. After over a century, they finally work it all out thanks to Sergio popping up and balancing them all out. It was a “right person, wrong time” moment, but they found their right time in the end. And Sage got his lifelong wish! The reveal was crazy. Omg, I could talk about this book, honestly all of Anna’s books, for forever, but just know it was fantastic and I highly recommend! ⭐️5 🌶️4 💧3 😂3 🐲🐉🦄🥵🔥👨🏻‍❤️‍👨🏼👨🏼‍❤️‍💋‍👨🏻🔡🪢⛓️🫃🏼🏡🧑‍🧑‍🧒 📍Iowa 🤍mmm 🤍omv(aoo) 🤍shaman unicorn shifter 🤍dragon shifter best friends 🤍second chance 🤍hurt/comfort 🤍fated mates 🤍mated to his brothers mates father 🤍mpreg 🤍heat 🤍knotting 🤍designation change 🤍magic 🤍paranormal romance 🤍hea Always check content warnings before reading!

Sage, Dexter & Sergio

If you’ve been following this series, you know that the fated mates pull in this world is intense and it’s 3x as much with this throuple dynamic. I adored Sergio, Dexter and Sage. The balance between the two protective dragons and their mate is so sweet. The Sanctuary is the perfect backdrop for characters who have spent their lives feeling like outcasts to finally find where they belong. True to Anna’s writing style, the spice is hot, but it’s the protective nature of Sergio & Dexter towards Sage that I really loved. Watching these two powerful dragons create a safe space for their mate while navigating the dangers that threaten their sanctuary was so moving. If you like: ✨ MMM romance ✨ Obsessive/protective dragon shifters ✨ Fated mates ✨ Hurt/comfort ✨ Found family vibes ✨ Mpreg

Three times the love

Dex’s long-awaited story was absolutely worth it, bringing together Dex and Sage who are both omega dragons who have loved each other for years but never acted on it, along with Sergio, a beta unicorn shaman who unexpectedly completes their bond and even transforms into an alpha. I loved Dex from book 3 so much with his attitude that I loved getting to know him more in this book. These three relationship unfolds in a way that feels both heartfelt and exciting. The dynamic between the three is sweet, funny, and full of chemistry, making them feel perfectly matched despite the odds. I loved seeing them finally get their happily ever after. Now I’m just excited to see what comes next in this series.
