Harper Tavros always dreamed of being a dragon rider. But after a prank went horribly wrong—she ended up bonded to an utterly ridiculous and insanely brave griffin instead. A bond that can only be broken in death. Together, Harper and Felix graduated the Tennessan Bonded Training Academy and proved themselves during their first six months on active duty even as the war with Savinia heated up.
Now, every mission is more dangerous than the last.
Griffin riders are the eyes and ears of the Tennessan military, an advantage unmatched ever since their enemy’s griffin riders vanished from the battlefield years ago. So when a dying Savinian griffin shows up at a Tennessan fort, Harper and Felix are dispatched to retrieve the message she carries—a plea for help from Savinia’s last griffin riders.
A plea Tennessan can’t afford to ignore.
Harper and Felix are assigned to the team tasked with unraveling the mystery of Savinia’s griffins. Their mission will take them deep behind enemy lines and into the dreaded Southern Smoke Mountains. After everything goes wrong, Harper and Felix will be pushed to their limits.
When every choice leads into the fire, their only option is to burn . . . and let the flames temper them into something stronger.
I really enjoyed Rise from Ruin, the first book in the Griffin Corps. I thought it had good characters, themes, humor, and action. I feel the same about this sequel, Tempered by Fire, and think that Melissa Olthoff not only played to those strengths, but improved on them. My only criticism is in the (lack of) plot in the middle.
Melissa is an excellent character writer. Her main characters of Harper Tavros and Felix are even better in this book. Not only are they distinct and fun to read about, but their banter made me laugh out loud many times while reading the book.
And it's not just the main characters who are well written. I thought that Keaton, Dimitri, Mayhem, Colonel Littleton, Aral, and even the Dragon Riven were all dynamic and fun to read about (although this series is clearly the Harper-Felix show)
Where I think Melissa really shined in book two compared to book 1 was in her themes, particularly her themes regarding the military. She explores themes about loss of fellow soldiers, about animal companions, about PTSD, and about rehabilitation. These are all explored masterfully well, and Olthoff uses the Fantasy elements to make the proverbial medicine of the themes go down.
One thing I appreciate is how Olthoff writes military fantasy. So many military Science Fiction (and even Military Fantasy) authors get way too bogged down in military customs and technical jargon that it makes their books unpleasant. While Military lifestyle is literally the point of this book, I never felt bogged down or that I didn't understand the relationships between the characters or what certain terms meant. This is how I want military stories to be told.
If you've ever met Melissa Olthoff or watched one of her interviews, you know that she has an infectious sense of humor. That comes through quite clearly in this book, and I think it's her best use of humor yet. The running joke of Felix wanting to eat cows is prevelant throughout the book, and you'd think it'd get stale after a while...it does not.
Olthoff continues to reveal more and more about the worldbuilding (something clicked about it in the final act that made me go "aha" and really has me hooked to unfold more in book 3). And we actually get to meet some Savinians in this book, which really helps one of my issues from book 1 of them being faceless villains.
There were also some incredibly emotional moments in this book. Olthoff introduces a griffin in the first portion of the book, and that sequence nearly had me in tears. And Olthoff basically replicates that scene later in the book...and I was so worried about what would happen, and it elicited the same emotion. (some would cry that this is emotional manipulation from the author, I'd say it's good storytelling).
There is one downside to this book, and it is unfortunately the same downside I had in book 1...and that's the plot in the middle. Book 1 had a decent hook in the beginning, and a decent pick-up of plot at the end...but it was really just training/military montages in the middle. This book has a really excellent first 120 pages of plot, and the plot in the last 130ish pages is quite excellent (I'd say the opening and final acts of this book are definitely better than the opening/final acts of book 1)... But there's a stretch of about 200 pages in the middle where the plot is yet again quite thin and I found myself frustrated, really wanting the story to move forward. There are little bits that Olthoff is clearly setting up for the final act, but I think it could have been condensed and had more story in the middle. I was still interested in her characters and world (something I cannot say I've had for other mil sf/f books with weak plotlines), so it was still entertaining. Still, could have been better.
So on character, themes, action, emotion, and humor, this book knocks it out of the park. It has a weakness in plot in the middle, but I think it's more than made up for in the story at the end and in how strong the other elements are. Overall, I'll give this book a 9 out of 10! Well done Melissa Olthoff.
I was lucky enough to be an eARC reader for the second installment of The Griffin Corps series.
Tempered by Fire absolutely pulled me in from page one and did not let go. This book was nonstop action in the best way—every chapter had me saying “just one more” until suddenly I was way too far in to stop.
But what made this story such a standout for me was Harpy and Felix. Their chemistry, banter, and the way their story unfolded kept me completely hooked. They were both such strong, entertaining characters individually, but together they were even better. I found myself laughing out loud so many times because their dynamic was just that good.
Melissa Olthoff did such a fantastic job balancing action, humor, and emotional moments without ever slowing the pace. I was fully invested in Harpy and Felix from beginning to end and loved every minute of their journey.
If you love fast-paced fantasy with unforgettable characters, sharp banter, and plenty of laugh-out-loud moments mixed into the chaos, Tempered by Fire is one to add to your TBR.
I was extremely excited to be given the opportunity to read the eARC for Melissa Olthoff's Tempered by Fire, published by Baen Books.
However, before I delve into the specifics of this book, I feel it is necessary to point out that the title is inaccurate, or at least grossly oversimplified. Don't get me wrong, I love Melissa and her books with a passion as hot as 1,639 stars but as I sit here writing this I feel a wildy uncontrollable anger, as intense as 1542 stars, building within me as I consider this title.
"Why does this title anger The One True Rob so?" you might ask yourself, not seeing anything that would cause the type of anger I've described. Prepare yourself, because when I point it out, you will likely fly into a rage and start looking for a place to riot.
Fire doesn't temper something, at least not by itself and when applied alone it actually makes steel lose its temper and become quite brittle. After reading the first book, Rise from Ruin, I naturally assumed that Harper's story would continue on to the next logical step and that book would be called "Forge Welding the Shards", as she continued to "pick up the shards" of her shattered life and reassemble them into something new.
The series should have the following titles. 1. Rise from Ruin (Published) 2. Forge Welding the Shards (The correct name for this book.) 3. Forging the Blade 4. Quenching to Stabilize the Crystalline Matrix 5. Tempered by Controlled Heating and Quenching 6. Grind and Polish 7. Final Touches, Etching, Sharpening and Quality Check
I know this is a simplified list, but this isn't a series of text books on every individual step of the smithing process.
Geez, stop being so picky and critical!
Now that I've let that all out, I am finally in the proper frame of mind to continue with my review of the pages behind the cover. I will pause and I partake of a Gingersnap of Gratitude, in celebration of moving past my rage.
Is everybody back?
Great!
Moving on to everything past the cover of this book, lets get the checklist out of the way.
Griffins - ✔️ Gryffindor - X Dragons - ✔️ Fire - ✔️ Tacos - X Accurate Portrayal of Cybersecurity - Sort Of
The way Melissa wove her words together on the pages caused hallucinations of best kind. I could smell the spicy musk of the griffins, or perhaps it was the freshly baked cookies. The sounds of combat rang out in my mind like grandchildren fighting over what game they wanted to play.
This book is a non-stop page turner, even if you're not ready for the page to turn. Melissa deliberately took the time to write a Kindle virus, I mean feature, that only gives you seventeen seconds to read each page and will not let you go back to that page until the entire book is complete.
I read books multiple times anyway, but this is the first time I've had to read one thrice to get the entire story and now I can't imagine reading it any other way. It was just one fun adventure after another.
My recommendation is that you buy this book and dedicate the time necessary to read it, as many times as it takes.
Another action-packed, character-driven masterpiece of fantasy from Olthoff. It is nearly a perfect Book 2 for a fantasy trilogy. The character trials provide meaningful growth, and the author drags them through tons of darkness and uncertainty as they struggle. Tempered by Fire is the Empire Strikes Back of the Griffin Corps series so far.
The Characters: Harpy, Felix, Oz, Dimitri, Keaton, Zayne, and most of the surviving characters from book one make at least a minimal appearance here in book 2. Harpy and Felix's bond truly gets tested as they navigate trying to help Keaton through his PTSD, figure out Harpy's love triangle, and finish up their training with Oz. I'm not going to post any spoilers, but you will find yourself reading well past your bedtime as they battle through the turmoil.
The villains really get fleshed out here in book 2. You are constantly looking for hints as to who is backstabbing who, and now we got even more information on the Mavens. I can't wait to find out more about these magical/mythical women.
The fact that some of the characters seem to be call-outs to real people makes me chuckle, and if that is all coincidental, just let me continue with misconceptions. They are perfectly fine fill-ins for how I picture the characters in my mind, and I don't need to be rethinking all that now.
The Setting: I love the post-apocalyptic Tennessee setting for the story. I recognize many of the locations, but I do need to figure out the modern-day equivalents for Stonehaven and the training academy's location.
The world-building in book two exceeds all the setup in book two. Olthoff starts filling in much of the history that got us to this point, and spins it perfectly into a new macguffin for book 3.
The Plot: The plotting for the book does go flat for a bit in the middle of the book while establishing the new unit, but that might be just because the start and finale are set at a breakneck pace. Those sections do generate unit cohesiveness so it's not like they could be cut, and those chapters are also the ones sprinkled with the mild spice notes for the story, so there is still plenty to look forward to while reading them.
There is plenty of humor sprinkled throughout the book as well. Don't go thinking from my review so far that it is all doom and gloom. All I will say without spoiling everything is "MOO!".
The spice is primarily all fade-to-black, so this won't be a book where you go looking for extra peppers to spice up your nightly reading before bed. I would recommend this book to all the fans of other dragon rider series like McCaffrey's Dragonriders of Pern, Novik's Temeraire Series, Paolini's Inheritance Cycle, or, on the gryphon side of fantasy, I see these filling the hole for those looking for more Mercedes Lackey's Gryphon Series of books.
It's a Baen trilogy, so I can't wait to see what the next 4 to 7 books have in store for this amazing universe!
I read the eARC for this, the second book in Melissa Olthoff’s Griffin Corps series, with an expected publication date next week of July 7, 2026. Tempered by Fire continues the story from last year’s Rise from Ruin. To recap the series, this is a post-apocalyptic world, with almost no modern technology but with the ability to breed dragons and griffins. There is a war going on between two competing geographic regions. Harper Tavros grew up always wanting to be a dragon rider, and as she nears the time to bond with her chosen dragon as the top dragon rider student, a school “prank” shatters her dream, as she is bonded with a griffin. Most of her dragon riding skills are useless, and she is kept back for a year.
This series is fantasy with a touch of romance, with incredibly rich development of the characters, including dragon riders, griffin riders, scouts, dragons and griffins. Harper’s mischievous bonded griffin, Felix, is a strong personality effectively pairing with Harper. The rhythm of a military academy was a highlight of the first book and demonstrates Olthoff’s experience in the air force. Tempered by Fire continues to demonstrate the dynamics and bonds within a military unit.
The book is divided into two sub story arcs. Part I is Burned by Flames. Harper and Felix are thrust into the ongoing war with neighboring Savinian forces. The Savinians continue to surreptitiously encroach on Tennessan territory. The military action, primarily of scouts and infiltrators engaged in guerrilla warfare is a strength of the book. Of course the action is enhanced with dragons and griffins in battle. In Part 2, Tempered by Fire, Harper and Felix are prisoners in a Savinian base located near poisonous alien laboratories. We learn what happened to Savinian’s griffins. There are double crosses, enemies that become allies, and plenty of intrigue to go around. Tempered by Fire is really quite masterful, with well written characters, compelling relationships, humor, and action. And of course, since this is a Mellissa Olthoff story there are shenanigans galore, especially among Harper’s former classmates and comrades.
I want to thank Baen Press, the publisher, for this eARC, and this is an honest review. If I did not make it clear, I highly recommend this book, and suggest you preorder, or at least add it to your TBR pile.
Addendum: As you may not know Melissa Olthoff is one of the 3 Feral Ladies [Melissa, Marisa Wolf, and Kacey Ezell] with a regular podcast. If you are a fan of any of these authors, I recommend checking out the podcasts. Following the release of Tempered by Fire, the Feral Ladies [minus Kacey] had a podcast with guests Charli Cox and Jody Lynn Nye. Check it out, Shenanigans were had.
Also, fun fact, the author mentioned that she based the different Dragons and Griffins on current US airforce airframes. See if you can match the dragons to their airforce equivalents.
Some bonds are meant to be broken, and others only grow stronger when they're Tempered by Fire. Have you ever read a book that made you call the author some very not-nice names? I have. Today is launch day for the newest release from my friend Melissa Olthoff. I got to beta read this book, and amazing doesn't even begin to cover it. There's this one really, really emotional scene (if you already read it, you know the one...) I'm talking box of Kleenex, ugly crying, and every curse word I could think of, because Melissa did something that I strive to do in my own writing. She made me feel things. I felt emotions: despair, anguish, loss, and 1 box of Kleenex wasn't enough. But, like Melissa does, she brings you down to the deepest, darkest depths, and then you get raised back up, alongside her characters. If you want to go on an emotional rollercoaster of a ride, grab this book. Better yet, get Rise From Ruin, then read them back to back. You'll thank me later!
Fantastic series for dragon and griffin rider fans!
Outstanding sequel. I enjoyed this more than the first. What I deeply appreciate is that the main relationship in both books is platonic, even though there's also romance between Harper and her love interest, its the relationship between Harper and Newton and how they're there for each other that keeps me going. I hope the series will continue!
Content warning for suicidal ideation in this book.
As engaging as the first. Melissa doesn’t shy away from the hard things, and isn’t afraid of making you worry for the characters lives. At one point it was touch and go for a minute, with hope given and then hope ruthlessly stolen and then hope given just at the end. Language yes, fade -to- black with minor details before it fades. There will be a third book.
Holy hell, this Story is fast paced. No "down time" rush of adventure, danger,love, and the epitome of trust. So good,hard to believe it's a sequel. Fully enjoyed this emotional journey. The hardest apart now is waiting for the next book. Thank you Melissa for being such an amazing, talented storyteller.
