I think my favorite part of this whole series was the worldbuilding. Tanria, the mists, the gods, the mythology, even the autoducks, were such fun and complex ideas that really makes this series unique. I love how Bannen explored so many different parts of the world without ever leaving Eternity so we still get to see our favorite characters but the story still feels fresh and new for each book. I really enjoyed learning more about the astral plane and the Gods in this one.

Rosie was such a fun character and such a different FMC from Mercy and Twyla. I was so happy to see Duckers and Zetty back in this one. I loved the sibling like bond Duckers has with Rosie, they made such a fantastic pair. I love how much this series which started with two very lonely people has basically grown into a giant found family.

My main down side was the almost insa-love between Rosie and Adam. I think in the second half of the book the relationship is more developed, but it felt off for our longest living FMC to fall in love the fastest.

I also didn't really connect with the feelings of wishing for mortality that Rosie is struggling with, which did play a pretty large role in this story.

As this is the final book in the series I will miss Tanria and the dragons that throw up glitter.

2.75 stars - Story
⭐️⭐️⭐️⭐️ - Narration

I wanted so badly to like this story but it was a struggle to finish this one. Honestly, if it wasn’t an audiobook I probably would’ve DNF’d
I absolutely adored the previous books in this series so I had high hopes for our return back to Tanria in Rosie and Adam’s story.
I’ll start with the things that I did enjoy. I loved seeing the dragons again and the glimpses into the past characters lives. I LOVED Zeddy’s return and would’ve absolutely loved if our MC’s were Zeddy and Duckers and we got an entire story of them. It was fun to watch their characters again but I definitely wanted more.
I think that the author did a really great job of switching the typical gender rolls (tall man and short woman) and showing how the perspectives and thoughtlessness of others has impacted Rosie as a 6 foot 5 woman.
I also really enjoyed the narrator. She did an amazing job bringing the characters to life.
Lastly, I really enjoyed the way that the ended. All of the characters throughout the last three books had their stories wrapped up beautifully.

Unfortunately, there was a lot I disliked about this book.
I felt no connection to the FMC and MMC. Our FMC Rosie was really annoying, I love a good no filter character but for a 150+ year old demigod the way she spoke was just cringey. I know this series usually thrives on its campiness and it’s honestly something I adored in the other books, but this one it felt forced and uncomfortable.
Rosie does have a lot of depth and I appreciate her candor, it’s fun and quirky but it just felt too over the top.
As for Adam, his character was like watching paint dry. I get why he is the way he is and I enjoyed seeing him find happiness. But, there was a complete lack of chemistry between Rosie and Adam that took away from their love story. It felt very insta-love which I don’t mind if it’s done right, this was just not one of those times.
The story itself really seemed to drag, it felt like nothing happened the majority of the book.

Overall, this book just really fell flat for me.

Thank you NetGalley for this audio ARC in exchange for an honest review

I really enjoyed this final book in the series. I will truly miss it. Rosie and Adam were wonderful characters and I was happy to see their HEA. The narrator was wonderful and did a good job keeping me invested. Overall a great book and audio.

I have absolutely loved the world and characters of Tanria since I read Hart and Mercy and The Undercutting of Rosie and Adam did not disappoint. This was such a sweet, funny, heartwarming book that gave Rosie her moment in the spotlight and gave such a beautiful cozy closure to the Marshalls of Tanria that we met in book 1, followed through book 2, and continued to love in book 3.

Yet another third instalment of a favourite trilogy being released this year and my god it was good! Keeping the same tone and feel as The Undertaking of Hart and Mercy and The Undermining of Frank and Twyla, this book focuses on Rosie Fox, an immortal demi-god that has popped up for brief appearances in the previous instalments but now takes centre-stage and her Tanrian Marshall partner - DUCKERS!! Thank god because this guy is the heart of the whole thing and always willing to give his friends a nudge if he think's they're being too shy or wilfully ignorant!

We pick up 10 years after book two and the dragon reserve in Tanria is thriving. Instead of corraling lost souls the marshalls are now mainly involved with general lawmaking and safety in the mist shrouded area, which after 157 years of life is wearing a bit thin to Rosie. Unfortunately the portals into and out of Tanria start having problems so it's time for Dr Adam Lee, inventor of said portals to come and sort out the problem! Hilarity ensues. Well not quite, but there are certainly plenty of laugh out loud moments in this book and I felt that Rosie and Adam's personalities played off one another really well. It was of course great to catch up with our other past main characters and see what they were upto after a chunk of time had passed, as well as get more of a background into the mythology of the Old Gods and New.

All in all I thought this was a perfect end to one of my favourite and hardest to explain fantasy trilogies in a while and I'm going to miss this world a lot!

The narration was really well done, I'd not listened to this narrator before but would definitely listen to other books voiced by them.

I wanted to enjoy this but I struggled to like any of the characters. I also felt no chemistry between the 2 MCs. The idea was good but the execution wasn’t there..
The narration was also not my favorite. I couldn’t get over the male voice done.

I was so excited to revisit the world of the Tanrian Marshalls, and the journey did not disappoint! I loved seeing characters from the first two books reappear in this story, and the uniqueness and intricacy of Rosie and Adam’s personal stories made for some very heartfelt moments. The narrators did an excellent job conveying Adam’s monotone personality and Rosie’s sass throughout the story. They also each did a great job voicing the other characters as they had dialogue. This was easy to follow along to and easy to listen!

Cozy, cute and so comforting.
This book felt like a warm hug.

I listened to the audiobook version and I loved the narrator. She captured the spirit of the characters perfectly.

Thank you Hachette Audio for this ARC!

4.5⭐🌶️

This book was absolute delight to read. I really like Rosie .she was absolute sunshine girl with little bit of daddy issues .Adam is stiff and mysterious. I love that she is taller then adam. It was cute. The side characters Ducker and Zaddy was incredible.

Plot was actually good. The last few chapters were really good. I loved it.The narrator really bring these characters to life. Variation in different characters voice was so good.

Thank you Netgallary and Hachett audio for the audiobook arc.

I really loved this unique story of found family, adventure and true sacrifice. Rosie was such a fun character and Adam was so sweet and selfless.

📖 Bookish Thoughts
This one didn’t quite deliver for me, but definitely wasn't a bad reading experience . I was just hoping for something a little more fun and romcom-y, with more of a fantasy quest vibe. The premise had potential and there were moments I enjoyed, especially the humor sprinkled throughout, but overall, it didn’t fully land. The pacing also felt uneven throughout the book.

I had a hard time connecting with both Rosie and Adam. Their romance, especially from Adam’s side, felt a little surface level and leaned into insta-lovey territory. I found the writing to be overly descriptive and repetitive at times. A large portion of the first half focused on Rosie’s frustration with immortality, and while I understand that was central to her arc, it started to feel like we were circling the same emotional ground. That said, I did really like Rosie as a main character. She was confident and had some genuinely funny moments. I just wish the humor that peeked through had been more consistent.

Do yourself a favor and listen to the audiobook! It was fantastic both narrators delivered and brought personality to the characters.

🧡What You Can Expect

Stars: 3.75 rounded up

I really enjoyed Rosie’s personality. She’s got sense of humor and heart, and I love the banter with the other characters, especially her cat. 🐈 Kacie did a great job narrating her and bringing out her ‘no-filter’ personality. Adam is a quiet, gentle soul and a classic brooding MMC.

The romance was a little too instalust for my taste. Rosie’s internal monologue spent a decent amount of time on her underwear collection and emphasizing how hot Adam is. 👙 However, I do think Bannen did develop the relationship more in the second half with deep conversations and sweet moments between the two characters, and I appreciated how their relationship had developed by the end.

I did not read the previous books in the series before reading this one. While I think it does work as a standalone, reading the other books would have made the world more fleshed out, and I think I would have felt more emotional connection with the side characters.

Thank you to Megan Bannen and Hachette Audio, Orbit for providing an audiobook. I am voluntarily leaving this honest review.

I liked this but didn’t love this!

I would recommend reading the other 2, everyone’s says that’s not needed but it really is to understand the world. Plus if so you will appreciate the side characters so much more.

Rosie the little sas pot is great and Adam and is seriousness they both complement each other so well!
I feel like there was a bit of info dumping at the start that made me really lose interest.
But then the last 25% made up for it l!

Would I read again? Probably not
Did I like it? It was ok!
Would I recommend? Not really, well I would but it wouldn’t be at my top of recommendations!

Thank you for the arc in exchange for an honest review!

I loved Hart & Mercy and Twyla & Frank. Now I get to add Rosie & Adam to this list. And while I was maybe a little more excited about Pen & Zeddie in this story, that did not discount my adoration for Rosie and Adam. I really enjoyed watching their connection grow. I thoroughly enjoyed diving back into this world and really enjoyed the narrator in this audiobook. I didn’t want to stop listening and went back to it every chance I had. I’ll miss visiting Tanria and the world Megan Bannen built. Highly recommend this third (and final?) installment of the series.

Thank you Hachette and NetGalley for an advanced copy of the audiobook in exchange for an honest review.

Kacie was amazing as the immortal demigod Rosie! Her different voices conveyed the unique personalities of each character. I laughed out loud at the banter and humor! Adam’s brooding seriousness came across as endearingly dry and adorably awkward. This was a heartwarming, cozy story that spoke to my anxiety. Rosie and Adam’s relationship was the slowest of slow burns with realistic character growth and a satisfying payoff at the end.

Thank you so much to Megan Bannen, Orbit Books, Hachette Audio, and NetGalley for this ALC!

The Undercutting of Rosie and Adam is a delightful listen that showcases Megan Bannen’s trademark wit and emotional depth — and the audiobook brings it all to life with flair. The narrators perfectly capture the chaotic charm of Rosie and the dry, quietly endearing energy of Adam. Their chemistry translates beautifully in audio, especially through the snappy dialogue and tender undercurrents.

The performance really enhances the humor — the comic timing is spot-on — but it’s the emotional nuance that truly lands. You feel every awkward silence, every moment of vulnerability, and it makes the slow-burn connection feel even more authentic.

A small deduction comes from occasional pacing inconsistencies — a few scenes that feel a bit rushed or tonally jarring in the delivery — but overall, it’s a highly engaging, emotionally satisfying experience.

If you’re into unconventional romances with whip-smart writing, layered characters, and voice actors who get the heart of the story, this audiobook is well worth the listen.

Hace ya tiempo que leí The Undertaking of Hart and Mercy, una novela cozy de antes de que se pusiera tan de moda este adjetivo. Y tenía pendiente las continuaciones, así que cuando tuve la oportunidad de acceder de manera adelantada al audiolibro final de la saga, The Undercutting of Rosie and Adam me lancé en plancha.


El tema de fondo de la novela es la inmortalidad y sus consecuencias en el aspecto sentimental. Cuando todos a los que has querido alguna vez mueren a tu alrededor, resulta muy complicado continuar teniendo relaciones normales con las demás personas. Un poco a Los Inmortales, pero bajado de tono. Rosie es hija de un dios y una mortal, por lo que no puede morir… Mejor dicho, no se queda muerta, porque morir lo que se dice morir ha muerto muchísimas veces, como cuando era una artista ambulante en el circo y su número consistía en… morir. Ahora trabaja como ranger en Tanria, pero una de las veces que muere mientras toquetea uno de los portales de acceso a este mundo, el portal se estropea de tal manera que el doctor Adam Lee, creador de los portales, ha de venir a repararlo en persona. Lo que parecía una reparación simple deviene en un problema mucho más complicado, que obligará a la evacuación de Tanria y a buscar posibles soluciones de manera desesperada.

Como los demás libros de la saga Hart and Mercy, el tono es divertido y comedido, es una delicia leer un libro de fantasía con su poquito de misterio, su muchito de romance y en general con buen rollo y ánimo para todos. Además la labor como narradores de Jim Frangione y Kacie Rogers es sencillamente estupenda, adaptándose como guante hecho a medida a un texto que se presta también mucho al formato, con sus diálogos chispeantes y sus personajes secundarios que aportan mucho a la historia.

Por ponerle alguna pega al libro, la ausencia de conflicto quizá le resta un poco de emoción, porque la mayoría de la historia se ve venir desde bastante lejos. No es menos cierto que aunque sea previsible, no es por ello una lectura menos agradable. Con detalles como la inclusión de personajes de las entregas anteriores, The Undercutting of Rosie and Adam es un final de saga estupendo.

This was a really cute cozy fantasy—fans of Legends & Lattes will find a lot to love here. There's that same warm, whimsical vibe where the stakes are more emotional than epic, and the charm sneaks up on you.

I went back and listened to the first two books in the Hart and Mercy series before diving into Rosie and Adam’s story, and I’m glad I did. Characters from the earlier books pop up, and the extra backstory helped the world feel more lived-in. It’s not required reading, but it definitely added to my enjoyment.

Kacie Rogers nails the narration. Her performance has this sweet, gentle tone that fits the story perfectly—nothing too dramatic, just the right balance of heart and humor.

If you’re looking for something soft, romantic, and lightly magical, this one delivers.

4.5 ⭐️
I truly loved this book! It was semi insta-lovey but they still had the slow burn to actually acting on those feelings.

The constant back and forth of if plans were working or not really kept me entertained and invested!
I also LOVED how much time Duckers had to shine in this book and how his ending resulted 🥰🥰🥰

Their love was fun, especially with the twists that happened. This book had me laughing constantly. This felt the closest to how I felt reading Hart and Mercy since the series started!

Also so happy to have such full details of precious characters and watching how their stories evolved so many years after they started!

Thank you to NetGalley, for providing me with an ARC in exchange for a fair and honest review. All thoughts are my own and are in no way influenced by early access to this title.

This one let me down.
I think the time jumps between books just don’t work for me. I adored Hart and Mercy, then Twyla and Frank and the community around them, but in this book it almost becomes a locked door book in the sense that we have a small cast with not much movement…

Normally this is great for found family, but I couldn’t connect to any of the characters - even Duckers who has always been the highlight for me.

Immortal demigod Rosie Fox has been patrolling Tanria for decades, but lately, everything has become boring. Especially when she keeps dying and coming back.

When all the portals begin to break down, uptight, stern inventor Dr. Adam Lee declares an emergency evacuation of Tanria. Unfortunately, Rosie and Adam end up trapped inside the Mist. Together.

I did not see the romance between Rosie and Adam even though I did find their interactions more steamy than the previous couples especially towards the end.

The book was boring despite the seemingly high stakes with boring repetitive activities and descriptions.
Sadly, this book felt like fan service to see the characters in one final book. A nostalgic hurrah that just really didn’t work.
