Shifter and Shadow

Twelve Houses #2.5

by Sharon Shinn

Part of the Twelve Houses series, Shifter and Shadow takes place between the end of The Thirteenth House and the beginning of Dark Moon Defender.

What really happened on Dorrin Isle?

Kirra Danalustrous is the daughter of a marlord, a celebrated beauty—and a shapeshifter with magic in her veins. After a disastrous affair with a married man, she has fled to the edge of the kingdom, to a small fishing village that has become a refuge for children dying from the invariably fatal red-horse fever. Yet Kirra has discovered a radical cure. She can transform the patients into animals who can take a medicine that’s poisonous to humans. But so many people in Gillengaria fear and distrust magic. How many parents will allow Kirra to save their children? And if Kirra saves enough of them, will she be able to heal her own broken heart?

Donnal is a peasant’s son who has been Kirra’s protector and companion for years. Although he’s always loved her, he’s always known she was destined to marry some titled lord and take her place in society. After watching her fall in love with another man, he has tried—and failed—to leave her. A shapeshifter himself, he has accompanied her to Dorrin Isle, determined not to take his human form again because he finds it too painful to be around the woman he knows he cannot have.

But Kirra needs him. So do the dying patients. And if he’s going to help any of them, he has to have the shape—and the heart—of a man.

About the author

I’ve been writing stories and poems since I was eight years old. My first poem was about Halloween: "What is tonight? What is tonight?/Try to guess and you’ll guess right." Perhaps this inauspicious beginning explains why it took me till I was in my thirties to sell a novel. It occurred to me early on that it might take some time and a lot of tries before I was able to publish any of my creative writing, so I pursued a degree in journalism at Northwestern University so I’d be able to support myself while I figured out how to write fiction.

I’ve spent most of my journalism career at three trade and association magazines—The Professional Photographer (which, as you might guess, went to studio and industrial photographers), DECOR (which went to frame shop and art gallery owners), and BizEd (which is directed at deans and professors at business schools). My longest stint, seventeen years, was at DECOR. Many people don’t know this, but I’m a CPF (Certified Picture Framer), having passed a very long, technical test to prove I understood the tenets of conservation framing. Now I write about management education and interview some really cool, really smart people from all over the world.

I mostly write my fiction in the evenings and on weekends. It requires a pretty obsessive-compulsive personality to be as prolific as I’ve been in the past ten years and hold down a full-time job. But I do manage to tear myself away from the computer now and then to do something fun. I read as often as I can, across all genres, though I’m most often holding a book that’s fantasy or romance, with the occasional western thrown in. I’m a fan of Cardinals baseball and try to be at the ballpark on opening day. If I had the time, I’d see a movie every day of my life. I love certain TV shows so much that knowing a new episode is going to air that night will make me happy all day. (I’m a huge Joss Whedon fan, but in the past I’ve given my heart to shows all over the map in terms of quality: "Knight Rider," "Remington Steele," "Blake’s 7," "Moonlighting," "The Young Riders," "Cheers," "Hill Street Blues," "X-Files," "Lost," "Battlestar Galactica"...you can probably fill in the gaps. And let’s not forget my very first loves, "The Partridge Family," "Here Come the Brides" and "Alias Smith & Jones.")

I don’t have kids, I don’t want pets, and all my plants die, so I’m really only forced to provide ongoing care for my menagerie of stuffed animals. All my friends are animal lovers, though, and someone once theorized that I keep friends as pets. I’m still trying to decide if that’s true.

Reviews

[Ellie · Rating 5 out of 5]

This was such a satisfying conclusion to The Thirteenth House! Controversially, the second book in Shinn’s Twelve Houses series was my favorite—the imperfect, messy characters were more compelling to me than the others (though I loved the other books too, don’t get me wrong!) However, it ended very abruptly and didn’t give much closure to Kirra and Donnal’s unconventional but really beautiful relationship.

I can confirm this book DOES tie up the loose ends of The Thirteenth House and executes it perfectly! Having Donnal’s perspective was very refreshing and confirmed why he was such an appealing character to me throughout the books, even though he was more in the background.

This was so incredibly satisfying. I just wish it had been longer.

I ordered it & I read it as soon as it arrived, not realizing it was a sequel - but it didn't matter because there was sufficient backstory. The only complaint I have is that it wasn't long enough - I want more immediately!

[Brittany · Rating 4 out of 5]

Shinn’s Twelve Houses series is one of my very favorite fantasy series, and there has always been an information gap - what happened to Kirra & Donnal on Dorrin Island? And now, so many years later, we finally know! I was so excited to hear about this book coming out.
Most of my enjoyment of this novella came from just being back with characters & in a world I know so well. I do wish it had been longer, and had given them more space to work things out, but it was a good story that answered questions I’ve always had.
I may pick up the next books in the series now to see how this fits with those, too!

4.5 stars. After so many years of nothing in this series, one of my favorite series, I was soooooo excited to read this story.

[Jillian · Rating 5 out of 5]

I just got into this whole series within the last year and being able to read this newly published addition was such a welcome surprise! This is a super sweet and satisfying story; filled with yearning, acts of kindness, apples, and people who love each other. Truly a balm for my soul. I have so loved being in this world and with these characters. Donnal the man that you are!

Plot Description (from Goodreads):

Kirra Danalustrous is the daughter of a marlord, a celebrated beauty—and a shapeshifter with magic in her veins. After a disastrous affair with a married man, she has fled to the edge of the kingdom, to a small fishing village that has become a refuge for children dying from the invariably fatal red-horse fever. Yet Kirra has discovered a radical cure. She can transform the patients into animals who can take a medicine that’s poisonous to humans. But so many people in Gillengaria fear and distrust magic. How many parents will allow Kirra to save their children? And if Kirra saves enough of them, will she be able to heal her own broken heart?

Donnal is a peasant’s son who has been Kirra’s protector and companion for years. Although he’s always loved her, he’s always known she was destined to marry some titled lord and take her place in society. After watching her fall in love with another man, he has tried—and failed—to leave her. A shapeshifter himself, he has accompanied her to Dorrin Isle, determined not to take his human form again because he finds it too painful to be around the woman he knows he cannot have.

But Kirra needs him. So do the dying patients. And if he’s going to help any of them, he has to have the shape—and the heart—of a man.

I have absolutely delighted in this series and these characters over the past five months! This final novella (which chronologically takes place between books 2 and 3) was lovely. I really enjoyed Kirra's fraught romantic storyline in Book 2, even though it involved cheating, because it was messy and thoughtful and honest. And it wasn't tied up with a neat bow at the end. This novella further develops her relationship situation in a moving and believable way. So much yearning! Such a keen awareness of how complicated love, in its many forms, can be! I adored it. I wanted way more than 200 pages of it.

Also, we finally get the mysterious Donnal's POV, and it was perfect. He's such a gentle, loyal soul. His heart has been bruised, but he continues to support Kirra as much as he can, and she patiently accepts the boundaries he places. It all just felt so mature and wise and poignant. Squee!

Ok, now that I am done effusing about the romantic elements of "Shifter and Shadow," I can add that the background plot itself was very satisfying too. I enjoyed seeing Kirra and Donnal team together to try to save as many children as they could, even if some of the scenes were a little repetitive. It felt realistic. And Lilah and Geena's storylines were rewarding. The revelation about Kirra's mother was unexpected but interesting, and I like how it illuminated more about Kirra's character, in that she would never act like that.

I can't help but hope that Shinn will now write more books in this world, since "Shifter and Shadow" just came out in 2025. She returned to this series after more than 15 years. Maybe she will be inspired to write a few more books?? For instance, have we truly gotten a book from Amelie's POV? Or let's go back and start all over with Senneth and Tayse. 😅 Even though I have a lot more Shinn to read, I will absolutely miss these characters. How soon is too soon to start a reread? 👀

[Molly Quinley · Rating 5 out of 5]

This addition to the 12 houses series after many years was a wonderful answer to many previously unanswered questions In Kirra and Donnal’s storyline. So grateful to be back in Gillengaria after all these years. 💜

[Karen · Rating 5 out of 5]

It’s been 17 years since Shinn last wrote a book in the Twelve Houses series, but it’s been a longtime favorite of mine so I was thrilled to hear she was coming out with a new one. This book takes place part way through the original series (which was trad published, but her new books have been published by a small press.)

Kirra is nursing a broken heart and wants to feel like her life is meaningful so she goes to Dorrin Isle to try to heal people of the supposedly incurable red-horse fever. Donnal is also broken hearted, but of course, where Kirra goes, he goes too.

This is a quieter book of the series with none of the battles of the other books. It’s much more about internal conflict - relationships and overcoming fear and learning to live your life with loss. I loved it!

This series should really be read in order - either chronological or publication order is fine, but this is not a good starting place.

Actual rating would be 3½ stars.

Wonderful

I missed Kirra and Donnal. They are two of my favorite characters in the twelve houses books. I'm grateful for this new chapter to their story.

[Susan · Rating 5 out of 5]

Possibly shouldn’t give this 5 stars by my own typical standards, because in truth, I don’t think it stands alone. I mean, sure, if you’ve never read another in this series, you could read this one and completely understand everything that happens in it, I think. You wouldn’t have all the political background, but honestly, it doesn’t matter for this story. You wouldn’t have the detailed background of who these people are and what’s happened between Donnal and Kirra that’s led them to where they are at the beginning of this story, but it wouldn’t hurt. You’d still follow the story and if you were going to like it you’d still like it, and if you weren’t going to like it, reading the rest two books that preceded this one probably wouldn’t make a difference. But, it’s helpful to have the two books that preceded this one. In truth, it’s been a long while and I only remember the broad strokes. I set this aside fairly early on and went back to The Thirteenth House, directly preceding this story and reread a significant portion of the end of it to refresh my memory on exactly what unfolded when and how, and it was nice to have that information close at hand as I read the rest of this. I’m sure the relationship stuff between Kirra and Donnal felt richer to me for going back through exactly what brought them to where they are at the beginning of this story. But what I loved about this story stands alone fairly well. I’m on leave from work today, mostly to catch up on rest, and this story of healing sick people and bringing hope to people who have had none was perfect.

Also, this is more Donnal’s story than anyone else’s, even though it’s Kirra who drives the broader action. It’s Donnal who affects the changes the reader comes to care about the most, and it’s because of Donnal that it feels like an overall win and happy ending. And, since I have read the rest of the series, it’s great because Donnal’s the only one of the core group from the first book onward who never really had a book or story of his own. He’s always the quiet one, always in Kirra’s shadow, mostly always content to be there. Which is fine, except there’s a jump from the end of the second book to wherever in the third book that he and Kirra come back into the story, and this story fills the emotional void from that jump perfectly. The void is Donnal’s. Kirra is the focus of the second book. We know her feelings as it ends, and she’s the one to tell her friends in the next book what happened between the books. But the readers never get anything from Donnal. This book gives us that.

And I liked Donnal. I’d always liked Donnal, but only got to know him through Kirra and the others. It’s nice to get to know him as his own person in this story. He’s utterly devoted to Kirra, always. But he is an individual and independent. And he does have skills and abilities different from Kirra’s beyond shapeshifting more quickly than she can. Come to that, I had a far greater appreciation for Kirra’s skills in this book than I remember having from the rest of the series. My recollection was that she’s a shifter, but not as swift as Donnal, almost as though in exchange for her healing gifts, which, while greater and more versatile than Senneth’s, I didn’t remember as being spectacular. She really shines in this book for both skill sets and her slower shifting seems more like it may be an accommodation allowing her to shift inanimate objects and other creatures in addition to herself rather than an exchange. I guess it’s watching Kirra through Donnal’s eyes and the eyes of mostly lower class people rather than the great political movers and shakers of the world they live in. She stands out and shines more here in some degree of isolation.

[Christy Matheson · Rating 5 out of 5]

I love, love, LOVE Shinn's work, balancing character development and believable romance, shades of grittiness without becoming grim, and accessible fantasy worlds. Her Twelve Houses series is probably the darkest, the most political, and the most vibrant characters. I love it.

This is not a stand-alone. It comes between two of the books in the series, giving us the personal context that happens while the plot carries on in the main series. Since the whole series came out a while ago (I've read it a couple of times) I went back to remind myself where exactly this action happened, and read some reviews to place myself in the series.

In Book 2, passionate, temperamental Kirra has an affair with a married man, pushing aside her patient childhood friend, Donnal. I was *shocked* how many of the reviews *slammed* the book because they didn't agree with Kirra's choices and didn't think the affair partner was a good hero. I agree with the sentiment, but to me it was always obvious while reading that Shinn, also, did not agree with Kirra's choices. I did find it kind of painful to read, but because a well-developed character was making bad decisions that were absolutely the sort of decisions she would make at that stage of her life, given her own background and assumptions. I thought it was obvious all along that the affair was not a romance, it was a plot disaster that would blow up in Kirra's face and make everything worse.

Which it did. Kirra makes some mature decisions at the end of Book 2, and comes back in Book 3 with some actual character growth.

This book is what happens during her growth and change. What made it really lovely was that it was entirely from Donnal's POV — all the main books in the series are rotating POV, so it was a different emotional experience to stay with Donnal. It is powerful character change and depth, both watching Kirra from the outside and Donnal from the inside.

This is a short novel, so the external plot was clear but uncomplicated. That suits, since readers know generally what happens from reading the main series. However, Shinn used several small plot arcs to constantly propel the narrative forward, always giving us enough external action to support the emotional journey, so the book never felt navel-gazing. That was enough, but there was one really, really excellent twist at the end—it's pretty incredible writing to put an unexpected plot twist in the middle of a series that the reader already knows well!!

As I said, I always admire Shinn's characters, but Kirra and Donnal were not my personal favorites.... until this book. It added layers and layers of depth, forcing the characters to make choices until you could see exactly why and how they must choose what they did to be true to themselves.

[Delaney Taylor · Rating 4 out of 5]

4.5 again! I read this in a few hours with my husband after finishing Dark Moon Defender and I'm shocked and pleased that Shinn came back to this series as late as she did--if the publisher didn't pick it up earlier, they should have.

Highlights for me MUST include seeing more into Donnal's head. He's been so difficult for me to understand until now. I'm grateful for the insight. Also Kirra's development and the way Shinn plays with a pair of foil characters at the island kept me so interested in what is honestly a story about a difficult and heavy crew of subjects: grief, hospice, despair, heartbreak, abandonment, prejudice and helplessness. I'm so impressed how Shinn manages to keep it light, innocent somehow, and honest but not unkind. Also, the identity twist at the end of a certain shifter completely took me by surprise --I honestly felt a little silly for missing it by the end but the satisfaction of the reveal was worth my pride. 😁👍🏻 And the big declaration moment, splendid.

Lows: My biggest complaint about this, like The Thirteenth House, is the repetitive nature of the format--where there it was balls and soirees, here it's in patient out patient appointments etc. and if the books had not been so much shorter than Thirteenth House, I think even in the midst of such drama and joys that it would've chafed me a bit. Also, I have mixed feelings about Geena. That's all I'll say to avoid spoilers.

Ultimately, I really enjoyed the rengineering of Kirra--highly preferable to her more reckless saga. And Donnal is an expert in difficult conversations. It makes me wish he'd had more of them before now. I looked forward to the continued unfolding of these characters since I have two more books in the series to read yet!

[Olga Godim · Rating 3 out of 5]

This was a departure from Shinn's usual story structure. There was almost no conflict here, no danger to the characters, no confrontation of any kind. Mostly, it is a self-discovery story, told from the POV of Donnal.
This short novel is a follow-up to The Thirteenth House, which was Kirra's story. This one is Donnal's story, and I'm glad he finally got a story of his own, even though it is as quiet and gentle as the man himself. People who know and love Shinn's TWELVE HOUSES series know what I'm talking about. People who don't, should start from the first novel of the series, Mystic and Rider, and read the books in their intended order. Don't start with this novel, please.
I have to be honest here: Kirra's story was my least favorite of the entire series. While I read and re-read the other novels several times, I had trouble finishing The Thirteenth House even once. Mainly, I don't like Kirra and I don't understand why Donnal loves her. She takes him for granted and treats him poorly. She reversed her attitude somewhat in this book, but frankly, her change of heart wasn't very believable. Donnal deserved so much better than to be considered second-best.
As to why I dislike Kirra, I explained my opinion of her in my review of The Thirteenth House.
Overall: not a bad story, but more of an interlude than a full-fledged novel. A worthy addition to the series though.

[Emma Rose · Rating 5 out of 5]

An infinity of stars. This is one of my favourite adventure + magic + romance + friendship series and I reread it every year, sometimes even twice a year. Sharon Shinn has the magic touch - her books are so cosy and full of hope and friendship and love, she's one of my favourite writers. I never expected this book - the other books were written so long ago - and it won't make sense to anybody but those of us who've read the whole series and wish Donnal had had his own POV book as he and Kirra try to heal as many people as possible on a remote island and secrets are revealed. This was gorgeous and sad and lovely and unmistakably a Twelve Houses book. And now all I want to do is reread the whole series in chronological order again with this better appreciation for Kirra and Donnal's full story. I'm just so grateful.

[Diane · Rating 4 out of 5]

This book falls between The Thirteenth House and Dark Moon Defender in the Twelve Houses series. Kirra Danalustrous and Donal have gone to Dorrin Isle where those with red-horse fever go to die. Since Kirra has a solution that will cure the fever since she cured both Lyrie Rappengrass of Rappengrass House and David, a young boy in Danalustrous, of the fever. Most of the infected are children, who are on Dorrin Isle with their parents waiting to die. Kirra explains what she can do, and one father immediately asks her to cure his daughter. Many are skeptical or leery of magic, but as time goes on, there are more takers. Other tings happen while Kirra and Donal are on the island, all of which effect them; but you have to read the book to find out.

[Nicole Luiken · Rating 4 out of 5]

Short novel taking place between Thirteenth House and Dark Moon Defender. I always felt as if a little too much happened off screen between those two books, so was delighted to hear there would be a new novel addressing that.

I reread the rest of the series in anticipation of this release so all the characters and relationships were refreshed in my mind. Unlike the other books we only see Donnal and Kirra in this one--and we get Donnal's pov! It is more of a character tale/less adventurous, but very satisfying to my romantic heart.

[Karen Rossell · Rating 5 out of 5]

Thank you, thank you Sharon Shinn

I loved this entire series, but the one aspect that niggled at my brain was Donnal and Kirra’s relationship . Especially after her affair with Romar, and the heartbreak all around. Thank you for giving Donnal a voice, and depth of character. I now feel I can unreservedly recommend this entire series. There is a wonderful sense of closure, but….I still would like to know what happens going forward in wonderful world Ms. Shinn has created (unashamedly begging for more!)

[Katie · Rating 4 out of 5]

I can't believe this was released the year I FINALLY read this series, haha. I was really excited to see it since Kirra and Donnal's story DID feel unfinished.

I . . . don't know that this really fixed that for me. It filled in some blanks, I guess, but still didn't ADD much. Yay for finally getting Donnal's POV, though we probably really needed Kirra's as well, at least a little. Her side of it has never felt explored enough, even in her book!

Four stars mostly for author affection. And it wasn't BAD.

[Barbara · Rating 5 out of 5]

Any Sharon Shin book is a good one

In this fairly short story, we are treated to Kirra and Donnel - both characters from a previous series of books about mistics. We are treated to mentions of many of the former people of those books, including the disease that was taking so many children. It's a story about love, bravery and how each of us must face our own fears, but it helps to have a real friend to help you through. I recommend this book as well as any of the 13th-house and mistic books.

[annapi · Rating 4 out of 5]

It's been 17 years since the last book of the Twelve Houses series came out, so I really remember nothing of these characters. But I still enjoyed this world and the story of the two shapeshifters who help a small community suffering from a disease with no cure except radical magic - and magic users are not always welcomed.

I was a bit disappointed when I realized this was a pretty short story at 178 pages, just a bit longer than a novella but not quite a full novel. No wonder I finished it in a day! It left me wanting more, and I hope Shinn continues to write more of this series.

[Laura Anne · Rating 4 out of 5]

I loved this series and reread the books several times (though oddly, the slightly related book, Fortune and Fate, remains my favorite). I wonder how long this had been sitting on the author's desk before she finished it. It feels like she wanted to tell this story, but it couldn't fit in the main series, so lingered half-written for a while. It is a novella-length and doesn't really include some of the character development that her main books do.

It does, however, fill in this missing chapter in the narrative & was overall enjoyable to read.

[Anjali · Rating 4 out of 5]

It's been more than ten years since I tore through the Twelve Houses series, so I remember very little about the characters or the world. That being said, I thoroughly enjoyed this novella set between books 2 and 3 featuring the mystics Kirra and Donal. This is a quiet story, and Shinn's storytelling and place-setting shine. The writing/editing is the best it's been since Shinn moved publishers, so hopefully that trend continues.

[Jennybeast · Rating 5 out of 5]

What a delight to read another story from the 13th house. I love the combination of everyday lives in a rich other world. I love how in this world, magic is unstinting, limitless in its way. I love that the trade off from wild shifting is a wild unsettled spirit. I loved that characters and the plot — what an idea, to be able to heal a terminal disease by changing someone into a different animal. So interesting, and a pleasant little love drama as well.

[Rebecca Tousey · Rating 4 out of 5]

Kirra and Donnal have this adventure before the confrontation between Amelia and the dark lady.

This filled in the space right before the uprising against Mystics.
I wish it was longer. I also wondered how Donnal carried money to buy fruit in his bird form. I guess he transformed it like he did his clothes.

[Mai · Rating 5 out of 5]

Oh, Sharon Shinn! How I love you! Kirra and Donal are so marvelous and have such depth of character - as all of your characters do. This is a wonderful glimpse into what happened on that island and a sweet look at Donal and Kirra together. Loved it!

gentle, sweet

a nice love story that helps to fill out the story line. So glad to see much was told through Donnal’s eyes, a character whose depth deserved to be explored. Bel’s role was unexpected…and a great addition.

Another Twelve Houses book? Excuse you? Excuse me? *throws confetti*

Ah, this felt so good. I understand why the series originally progressed without two Kirra-centric books in a row, but I sorely needed this short little moment to resolve the tumult of emotions that was book #2.

Perfection!

I love reading almost anything Sharon Shinn writes, but a chance to revisit an old world with new content. Perfect. Existential questions and the ordinary of life paired to perfection. Thank you!
