ARC REVIEW:
5⭐
WOW!!!

🍃 Everything about this book is so well thought out, well planned, developed, and written. I'm genuinely blown away with this world, the magic system, the history of the Fates and the Creator and the steward magic. The idea of a portal fantasy is unique and one I haven't seen done a lot, and so captivating.

✨ The Christian themes were so wonderfully present throughout the book! The Creators do clearly resembled the Holy Trinity, and the energy renewal reminded me of manna in the old testament. It was brilliant!

💚 Scout, our FMC, was an easy character to root for. She's just a normal girl with normal likes and dislikes who is thrown into this different world, alone and with magic. She's confident in herself and strong-willed. Despite her confusion and feelings of isolation and discomfort, she pressed on. Her strength was admirable. Since she was new to the world and didn't know ANYTHING, she had to learn a lot. It was a nice way for me as the reader, to learn things as people told her them for the most part (Alaric's pov definitely helped)

🍃 Speaking of... Alaric, the MMC, is everything you could want, honestly. He's fierce and mysterious and a fire-steward for Pete's sake. And in the words of Scout, "he's hot". Literally and figuratively 😉🤭 But besides that, I really felt for him. He's an outcast and most everyone treats him awfully 😭 I wanted to yell at them that "he's not your enemy!!!!!". I also love his bond with Mireille--the healer oozed comfort.

✨The "imprint" idea?? LOVE 😘 Like the way they felt so drawn together was amazing, their chemistry and tension was so good. I also love how he can read minds, there were a couple scenes where she thought about him and he was like 😏😏😏 LOLLLL it just adds another layer to their building relationship

💚Also the magic system and world 🤯🤯🤯 how the different factions each have different gifts and specialties, their traditions, how they harness magic, and the channeling magic were so cool. SO in depth.

🍃The writing was witty and easy to understand and it's just so well written overall. The author really knows how to write characters with depth.

✨All the characters invoked feelings. Like you either loved em or hated him and that's exactly how a book should be. It was so easy to get sucked into this story and this world, I literally could not put this book down! Like I could gush about this book for days, oh my goodness, y'all.

💚I wanna write so much but I can't spoil anything 🤭🤭. Just know that I was shocked and sad at the end. can't wait for book 2!

This was one of those stories that pulls you through the pages and quietly refuses to let go.

Through The Green Glass Door is a portal fantasy with rich element magic, a perfectly balanced grumpy sunshine dynamic, found family, and writing that feels almost lyrical at times. The descriptions were so vivid and intentional that I didn’t just read this book, I stepped into it. Every setting felt alive, textured, and real, like I could reach out and touch it.

The magic system was immersive without being overwhelming, woven naturally into the world rather than dumped on the page. If you love portal fantasies, magic that feels elemental and powerful, and are needing a unique new adventure this one is absolutely worth your time.

I cannot wait to see what happens next!

If you are looking for a YA portal fantasy with a reluctant heroine and elemental gifts, and of course with a love story thrown in, this might be your next read. Katie Zeliger creates a world I want to visit and can't wait to read more about in the next book.

Scout is dragged to England to spend the summer with her great-aunts who she doesn't remember. She assumes this summer between high school and college will be boring.

Boy is she wrong.

Her family has some mysterious history she begins to slowly uncover while she's there - but the greenhouse and the pantry are strictly off-limits, and Aunt Zelda doesn't even want her looking at a photo album. There's also something about a secret book...and her eccentric aunties, though completely opposite in personality, seem united in not telling her everything she wants to know. She learns more than she bargained for when she somehow ends up stepping into another world where people have elemental gifts and she catches the attention of one fire-stewarding man in particular.

The girl who didn't think she'd ever belong anywhere finds people she feels like she belongs with but has to decide if it's worth the risk.

Scout comes across as a genuine teenage girl, with all the emotions and confusion that comes along with it. She's relatable and likeable, as are her parents, aunties, and other characters in the book. My favorite part of the story was seeing how the people in the other world used their elemental gifts (and one or two other things that happen there that that I don't want to spoil!). The villain is crafted in such a way that makes even the reader's heart fill with dread when thinking about her. I was invested in the characters and what happened to them - and might have laughed or gasped out loud more than once.

I appreciate that the ending, while clearly not the end of the whole story, came at a good stopping point. That being said, this story will still be living in my head rent free until the sequel comes out because I am emotionally invested in the main characters and the worlds they're from (both our world and the world created by the author).

I recommend this book to people who are looking for an exciting story involving fantasy, alternate universes, elemental gifts, romance (actual romance, not smut), and plot twists. It's not high fantasy but it's fun and exciting.

Notes from a grammar nerd/editor: I read this book before it was proofread, and there were several times grammatical errors pulled me out of the story. However, the story itself was constructed well enough that I didn't have any trouble getting back into it. I expect the errors will be caught in proofreading, so I have hope this will not be a problem for future readers!

I gave this book four stars because it is a very enjoyable story with believable characters and lots of excitement (especially in the second half). While not life-changing, this book did hook me. I would probably re-read and I do recommend it to anyone who enjoys this genre.

4.5 ⭐️

I've recently realized that portal fantasy is not my favorite type of fantasy, simply because I prefer to fully submerse myself in a different world, and I don't like knowing the characters could stumble out of that new world back into this one at any time (which is probably why The Horse and His Boy was my favorite of the Narnia books, because it didn't have that element). With that said, I thoroughly enjoyed this portal fantasy. Let me tell you why.

I found Scout (the FMC) to be relatable and realistic. Her character immediately pulled me into the story, and there were enough mysterious elements surrounding her and her aunties to keep me invested right from the start. I also enjoyed her struggles once she "fell" through the portal, and the way she learned and grew through them.

Alaric (the MMC), is a troubled character, but one I felt compassion for. I liked that his character took time to soften, to reach the point he did by the end of the book. If it had happened more quickly, I think it wouldn't have felt right. He has a lot of trauma haunting him, and reasons to keep walls up. But there were always little glimmers of someone else, someone who yearns for love and connection, underneath the fiery (literally) exterior.

The world building, descriptions, and overall storytelling were great, and I think fans of portal fantasies will appreciate this one (and even not-so-portal-fantasy fans, like me 😉). A solid debut! I look forward to the second book, especially after that ending!

First review and read of 2026. What a wonderful book! I really like it when writers use the hook of that side of the family you don't know, a side that holds more mysteries than answers. Scout is one of the most sensible and realistic protagonists I've read in a Portal Fantasy story. How far would you go to return home?




Characters
This, for me, was one of the strongest points of the story. The secondary characters really had presence, but without overshadowing the main ones. Scout deals (without giving away any spoilers) with one of the most real problems for a young woman about to graduate: following or rebelling against the expectations of others. Although she was sometimes compliant, she brought out her inner warrior in many scenes.

On the other hand, Alaric remained a mysterious figure for most of the book. Although I wanted to know more about his past, I appreciated that not everything was revealed because it would have been too much information. Also, I really enjoyed the interplay between the two narratives at the end of the book. The author knows what she's doing!

By the way, I'm already eager to see more of the true villain in the sequel. Finally, not someone morally gray, but purely evil, based on what they showed. This is going to get interesting 🔥



Worldbuilding
There was very interesting lore from the beginning. The concept of this new world is different from others I've read, however, I felt they explained more than demonstrated how things worked. I was more intrigued by the family secrets.


SPOILER Section:



Romance
Strangers-to-lovers, slow burn, dreams, no spice, communication. I'll leave it to your imagination to go read it 💗😉



Conclusion
I'll definitely be waiting for the sequel. There's so much potential in the unexplored elements. Also, something tells me there's going to be a lot of yearning in the next entry. It's for everyone looking for a breath of fresh air in this Portal Fantasy area. Thanks for the Arc! Also, congratulations on the debut 🔥🎉😄

Thank you so much, Katie Zeliger, for the opportunity to read and review an ARC of your debut fantasy!

I had a great time reading this. I will definitely be grabbing a copy for my shelves once it releases. Through The Green Glass Door travels from the US to the UK where during a summer visit with her aunties, Scout, a college bound senior in HS, discovers family secrets and accidentally slips into another world altogether.

The story gave me a bit of the nostalgia of Narnia while being fresh with elemental magic and Christian themes woven into the narrative. I loved her storytelling and feel like the author did an excellent job building a creative new world and magic system. I stayed up way too late to finish reading this and had to ruminate over the last several chapters all day before I could formulate thoughts for this review. That kind of ending is the best, and I am so excited for her to continue this series because I am already itching for book two.

You will definitely want to grab this.
And, the cover art is absolutely stunning!!

Well Done & Congratulations Katie on your Debut!

💖 no spice
🤭 minimal (if any? I can’t remember) explicit language
C/TW: death, murder, loss of a loved one, mild war themes, corrupt leaders, drugging

This was such a fun story! It follows a recent high school graduate who visits her aunts for a summer, and accidentally goes through a portal to another world. I loved the cast of characters and how the story unfolded! There were so many tiny twists and turns throughout. I think any high school student would love this book!

Language: none
Violence: mild terror and wounds
A few very brief mentions of drunkenness, Vivid dreams and terrors, A family thought to be cursed, as they are bonded to a greenhouse as gatekeepers of the portal. The family is thought to be witches by the town but they are not and explicitly says those practices are wrong. There are some traditions/rituals/ceremonies from the fantasy world, nothing violent or creepy.
💕Romance: There is a romance thread as the book progresses, and one kiss at the end of the story. It’s very cute and sweet.

My Age Rating: 14+

I really liked this whimsical tale! I believe it’s going to be a series, as the book ended on a cliffhanger! If Through the Green Glass Door interested you, go check out Katie Ziegler’s page! This book releases on January 26th.

If you are looking for a good up and coming fantasy book this one is great! My friend @overbookedandunderpaged gave me the amazing opportunity to beta read her book! It was such a great fantasy and I can’t wait for it to come out!

The story was so in depth and well thought out! I was drawn to the world and wanted to learn more about what was happening and its secrets. The writing made all the scenes so picturesque and you felt like you were there in the story! It was also unlike anything that I have read yet in my reading journey. It was so great to have a story that felt unique!

The characters were well developed and you felt connected to their stories! I also can’t wait to see more from the FMC and MMC🤭 (trying not to spoil literally anything lol)

I would say more but I don’t want to give too much away about the story before the release date! Seriously go check this author out and her book! She also has some amazing aesthetic posts on her page that helps you get an ever better idea of the vibes for the story!

Oh man, what a journey with this book! I have to admit, it took me a while to get invested. Whether it was just my busy life season or a lack of interest in a modern day girl with an attitude (I get plenty of that in real life), I’m not sure, but once she went through the portal into the “mirror world” - I was hooked!
You definitely get attached to the main female character, Scout, and the main guy, Alaric. Their outcast style bond makes them an interesting pair that you root for as they try to figure out what is going on in their lives and who to trust as they try to find out the truth, while fighting for their lives.
I felt like this story was a good mix of Divergent and Avatar the Last Airbender with just a small touch of X-men thrown in - at least those are the fandoms I know that I can compare it to. But an original take on pieces of those stories that was well done.
The main downside - now I have to wait for the sequel!

Rounded to 4⭐️

Portaaaalll fantasyyyy ahhhhh!!!

I loved how atmospheric this book is. Before entering the other world, the mystery builds and we only get bits and pieces, but that really only adds to the moments things come together!
I loved the market and other indications of the world’s colliding or the thin spaces that allowed them to kinda merge.

Glimpses into MMC Alaric’s world, Landow, were my favorite. He and several elements to the story rather reminded me of Zuko and Avatar: the Last Airbender.

My biggest thing, I wish there had been a bit more development in some areas.

Like her dad telling Scout more or she found something before she even met them, or we’d gotten more glimpses into conversations or her spending time with them so we felt what happened between them a little deeper. Like Scout’s reaction didn’t quite seem… as justifiable?
Also with Moss, I wish we’d gotten more interaction with her since she and Rhydian are who Scout grows closer too but I dunno, certain things didn’t hit me as I think they were supposed to? Admittedly, my attention was kinda divided with holiday goings-ons so maybe I was just distracted.

There are so many unique aspects I loved: how families worked and their connections. The different powers and lore.

The ending was amaaaazing!! Several things I wasn’t expecting! I was glad that it ended with definitely wanting more but it’s not such a cliffhanger to be angry the next book isn’t out yet, ha!

A great debut from the author, who shared ARC’s and I’m so glad to be on the team for! I was not required to give a positive review, all opinions are my own.

Stars: 3.75

Big congrats to Katie on her debut novel! Through the Green Glass Door is full of secrets, tension, suspense, elemental magic, threats, found family, and more. Katie created an interesting world and magic/gift system which I liked. I also enjoyed her descriptive writing; I could really picture the story in my head. This is an interesting, unique read!

At times, the story felt jumpy or disjointed. It also felt like lack of communication, stubborn secrecy, and/or miscommunication drove some of the conflict; I would have loved for more listening and talking things out to allow for depth (rather than mistrust) to grow in relationships. I wanted more conversations between Scout and Alaric, too. Some parts of the story, characters, and relationships felt wide but not necessarily deep (if that makes any sense…).

This is a slow-build, slower-paced story (emphasis on history of land/people, including flashbacks and dreams), and I get why. This is book one of a duology, so the main conflict and resolution will take place in book two – maybe that’s where some depth will come, too. It’s still engaging, but honestly, the action didn’t really pick up until the last quarter of the book. If you don’t like cliffhangers, I would wait to read this until the duology is complete.

Overall, I enjoyed reading Through the Green Glass Door, and I’m excited to see what Katie does in book two to conclude everything!

Content: violence/death (not overly graphic), abuse (physical, mental, s*xual) in a character’s past - not described in too much detail, danger/peril, clean romance, clean language but 2 instances of using God’s name in vain, magic seen as a gift

I received an advance review copy from the author, and I am leaving this review voluntarily.
