Phantom Queen

Ouroboros Academy #3

by J.B. Trepagnier

So, the brilliant part of our group is stuck as a jackal as we try to figure out the Forsaken Ones and how to kill them.

Whatever Morgana and the witches did seems to be preventing them from hurting people for now, but Morgana said it's just a bandaid. Nearly anyone else wouldn't be able to undo the binding spell if they found it, but someone with Void powers could just suck the magic out of it.

We're narrowing in to who the other Forsaken is in this life, but we also have to figure out how to do what the old gods couldn't and get rid of them for good this time.

This is the end of Sage's trilogy. The next 3 books will feature Iman as the FMC

Genres: Paranormal

Phantom Queen is most definitely my favorite book in the series. I had so much fun reading this one. The mystery got bigger, there's more of JB's trademark humor, and the romance was perfection. Normally, I would read this in a day, but unfortunately, life interrupted, so it took two days. I didn’t want to put it down. Surprisingly, Lucian has grown on me. Khalid is doing great, and my little psychopath, Liam, is up to the same old antics. Seriously, most of the scenes that had me cackling were because of Liam. Sage is most definitely benefiting from her mates. Things are getting steamy, their bonds are growing stronger, and everyone is working together. I love how much they respect and care about Sage.


The plot was incredible. We know the 'who,' but the 'why' took a minute to work out. The mystery just kept building. Honestly, I never would have guessed the reason behind everything, but after the big reveal, everything made sense. There was a nice twist that I didn't see coming, and characters who were originally minor started playing pretty important roles, which was unexpected but not unwelcome. Sage's roommate, Iman, was more present in this story, and things with her were very interesting. She has a mysterious background, and there are some new developments in her life I would love to know more about. I would love it if she got a spin-off. Phantom Queen was an amazing read. All my questions get answered, and everything gets resolved in an unexpected but satisfying way. Ouroboros Academy was another great series by JB Trepagnier.

As an avid fan of reverse harem and fantasy books, particularly with academy settings and high stakes, Phantom Queen: Ouroboros Academy Book 3 was the finale I had been eagerly awaiting for Sage's trilogy. And it did not disappoint in bringing her journey to a thrilling and satisfying close!

Sage and her MMCs are up against their biggest challenge yet: figuring out the Forsaken Ones and how to kill them, especially with one of her MMCs stuck as a jackal. This added a unique layer of urgency and emotional depth to their quest. I loved seeing their brilliant planning, the clever use of Morgana's bandaid spell, and the looming threat of someone with Void powers undoing it all. The stakes were incredibly high, and the author did a fantastic job of conveying the immense pressure on Sage and her pack to succeed where even old gods had failed. The unraveling of who the other Forsaken is kept me on the edge of my seat.

The dynamics between Sage and her MMCs felt well-earned throughout the trilogy, and this final book truly solidified their bonds. Despite the immense magical and existential threats, their personal connections and devotion shone through, reminding me why I love this pack. The action was intense, the magic was intricate, and the overall narrative was engaging from start to finish.

My reason for a four-star rating instead of a perfect five is that, while the conclusion for Sage was immensely satisfying, I felt that with so many complex magical elements and the immense scale of the Forsaken Ones, some of the resolutions, particularly surrounding the ancient gods' past failures, could have had just a tad more expansive explanation or more visceral confrontation. It's a minor point, as the focus was rightly on Sage's immediate fight, but my personal love for deep lore made me wish for just a bit more insight into the truly ancient powers at play.

Nonetheless, Phantom Queen is a powerful and fitting end to Sage's story. It's a must-read for fans of the Ouroboros Academy series, offering thrilling action, complex magic, and a deeply satisfying conclusion for our warrior queen. I am now incredibly excited for Iman's story in the next three books!.

I enjoyed this series but the final book in this trilogy this was just a little too fast paced for me to rate it as highly as the first two. As much as I enjoyed the mystery around who was who and finding out what the Forsaken Ones end game was, I missed some of one on one time with Sage and the guys. Knowing there are more books to come it made sense that the additional characters played a part but I just felt my attention was divided a little keeping track of everyone. I did love Darian but Adrian get a special mention though; he definitely feels like he is going to be the Liam of that group!

I loved Liam and the return of his shiv making combinations, Lucien's acceptance of his bromance with Liam, Khalid's calming energy and how they all orbited around Sage. The reveal of the glucose monitoring was handled brilliantly and Liam translating for Lucien after his first bat shift was cute. Sage stepping into her power was great as was seeing the plan come together even if it felt a little rushed in the last couple of chapters. There were a couple of reveals towards the end and I'm intrigued to see where Iman's books go next as she definitely has her own story to tell.

My interpretation of the star system;
3 stars - I enjoyed it; would read the author again
4 stars - I really liked it; I am invested and definitely want more from this author/series
5 stars - I loved it; I engaged with this book completely until I finished it and it is one I will re-read.

This is book 3 of Sage's story, you need to read book 1 and 2 first...
I loved Sage and her guys' story. It was fast paced, had humour, banter, a sprinkle of spice (this may start with a severed dick on a pillow and some characters are horny young adults but there are not too many spicy scenes...) over all it is such a good time! I also appreciated the style/tone of the writing being a bit different for each POV.

Sage and her guys are now ready to end the threat on Ouroboros Academy and with the help of all their friends will fight to the death to save everyone.

Just a warning, the end felt a bit "Oh, that's it?". Rushed isn't the right term but it felt like it could have been a bit better...
I'm looking forward to more in the world or Ouroboros Academy and following the adventures of other characters we meet in the 1st trilogy.

An amazing finale of Phantom Queen. It has everything I wanted and more.
We find out something important about Sage.
Khalid, Sage, Lucian and Mazen need to learn to shapeshift properly.
We meet a couple new people and one is going to very important in defeating the void.
We learn a few things.
They get help and it is epic how they get the void's phone.
It is encrypted into modern texts but not normal texts.
They get everything in place.
Then it is thrown into chaos.
We find out why the book is called Phantom Queen.
An excellent ending.
I a glad Sage got to have better relationship with her Mom.
Can not wait for the next series.

I have been enjoying the trilogy so far, but the ending of this book just felt like a let down. The tension built, but it was over very quickly, and we were left with a brief epilogue of sorts. I do love the characters, especially Liam and his were-corgi obsession, but they felt more… scattered (?) in this third book. The plot thread concerning Sages deadbeat dad had promise, but was relegated to being just a blip in the end with everything being wrapped up as quickly as possible. In the end, this just wasn’t what I was hoping for (although I will reread the trilogy as I do most of her books).

3.5 ⭐️

Final book in the trilogy and I only read it cause I wanted to know how they killed the forsaken .. and honestly it did not deliver.

I mean yes they won but there could have been so much more and basically that’s how I feel about the whole book. The first book drew me in, the second one I had to skim back over for the ending so that I knew what was happening at the beginning of the final one.

So many side characters and groups brought forward and then kinda just left. This felt like a surface level book that was missing depth.

The final book of this portion of the series. It is always exciting to see the school name school show up for the next read. I enjoy the characters and the story. There were moments I wanted everyone to be quiet, especially when it felt like the characters were trying too hard. At those times, I went and did something else so I could come back to dive right back in.

Portion 1 mystery solved and the next portion with focus on a different batch of known characters and further down the rabbit hole.

Hopefully, we will get more answers.

The characters were very appealing and complex and complicated and absolutely perfect together. Plot was intriguing and intense and well paced. World building continues to excel and impress. All in all a satisfying conclusion to the trilogy. Thoroughly enjoyed and highly recommend.

Grab a copy, kick back and enjoy!.

The Final Showdown
Sage, Liam, Lucian, Khalid, along with their extended group of friends know who the big bads are, but they don’t know what they want and why they are killing. This story wraps up Sage’s trilogy - I found it to be a satisfying ending, though a bit short of romantic action and a bit high on tangents. Overall, a solid read.

[Michelle · Rating 5 out of 5]

Phantom Queen is the final book in Sage's trilogy and a great addition to the Ouroboros Academy series. Sage and the guys' story is a fast paced, reverse harem, Academy romance with magic, mystery, danger, humor, fun banter, steam, unexpected twists, and so much more. A great ending, and I am so ready to read the next part of this fabulous series. I voluntarily reviewed a copy of this book.

So this is a really good book. In my opinion I like all the mixed culture and the pantheon that’s mentioned i and the academy is reallydiverse. I can’t wait to read the next books that are coming out even though I’m sad that this is the last book for these characters.
