Fi has toppled immortal beasts. Antal welcomes being conquered.

After helping the Lord Daeyari reclaim his territory, semi-reformed smuggler Fi dons a daunting new role: rebuilding a city alongside her monstrous partner, a haven free from bloody sacrifice. So when Antal’s father unexpectedly summons him home, Fi’s first instinct is to ready her claws.

Only, claws won’t be enough for this adversary.

Antal faces his first homecoming in five decades, dreading two truths. From his father’s seat on the governing council, he could undo everything Antal has built. And their last argument ended with Antal’s lover dead on the floor.

But a greater danger lurks: the appearance of a creature that even the daeyari fear, burning its way through the Planes. With Antal’s father leading the hunt, he and Fi must ally with a team of immortals who could turn fangs on them at any moment.

Or worse, strain their still-fresh love until it snaps.

From the author of Voidwalker comes the conclusion to the Beasts of the Void duology where spicy monster romance meets the epic fantasy of the Cosmere.

It’s funny that this is grumpy-sunshine, but she’s the badass even though he has the literal claws.

Review:

As the new partner of an immortal territory lord, Fi has a ‘public obligation’ to act ‘respectable’. Fi, with her rainbow hair, chaotic energy, and tendency to bite back whether human, leader, or immortal carnivore beast.

I love how both Antal and Fi have sharp edges, but soft insides that they will fight tooth and nail to protect for the other.

‘Once the butterflies settle? You have to wade through the mud again. You have to find ways to live together. Sometimes, that means bending a little to fit your partner better. Sometimes it means supporting the shit out of them while they do their own thing. You have to figure out which version will get you through this.’

I appreciated that, although there was a happy ending to book one, Antal and Fi must live with this change and try and shape it into something sustainable.

Antal finally feels some semblance of belonging and safety, yet misses the sense of home.
No human city can replace his plane, the comfort of twitching tails and his own language despite Fi learning (lots of bad words).

We also get some tender and harsh family moments - blood and found. Of course, Fi almost gets eaten by Antal’s father which makes it all the more complicated…

This one felt a lot more brash, hornier and contained waaay more cussing than book one. I didn’t love that as it often felt over the top and crass. Don’t get me wrong, I love a bit of chaotic energy, but this was slightly too in-your-face for me.

Fi’s arrogance did grate on me, but her thoughtfulness compared to book one developed into a double-edged gentle sword.

Like I said of book one, this is not the cosy romantasy that was The Phoenix Keeper, but I always appreciate the themes MacLean covers with girl boss characters.

Hello, it's me! The author!

I'm so excited to bring you the conclusion to the Beasts of the Void duology. I consider VOIDWALKER to be very much Fi's book, focusing on her home on the Winter Plane, her journey to forgive herself, her path to reconciliation with Boden and Astrid.

SUNSPLITTER is Antal's book. Fi is still our prominent heroine of course, still eager to face down immortal beasts she definitely shouldn't be yelling at. But we'll see much more of Antal's home on the Twilit Plane, and the strain of his relationships with the family and friends he left behind.

In book 2, you can expect:
- Our beloved bi4bi ship trying to figure out how to function as a couple
- So many daddy issues
- (Help, I called the antagonist Daddy Antlers on Instagram, now all the readers think he's hot and they can fix him)
- 33yo angry mongoose FMC determined to prove she doesn't need fangs to be intimidating
- Carnivorous immortal who is lowkey afraid of her (but he's into it)
- More sassy Void horse saving the day when we need her most
- Found family that makes me cry a little
- "I'll have you know that I'm God's favorite"
- Way more tail action

And of course please take care of yourself as you read.

Content warnings:

This novel is intended for adult audiences. It includes multiple scenes of explicit sex between consenting adults, including bite play, argument sex, wrist bondage, anal sex, double penetration, and pegging.

The non-human, immortal race in this world are obligate carnivores, with humans as their primary food source, including on-page description of a human being killed then eaten. Graphic violence includes bite wounds, burn wounds, dismemberment, and beheading.

This book centers, as a prominent storyline, the abuse of a child by a parent. This abuse in primarily in the form of emotional manipulation and verbal abuse, with two brief instances of physical violence (one past, one present).

Actual rating 4.5

I often worry about book 2 following a phenomenal book 1. I've had some terrible follow ups that have left me hating the entire series, some which were ok but didn't live up to their first offering and some that were right up there with the initial story.

I am so very happy to say that Sunsplitter falls into the last category. I devoured this book in 2 days and struggled to put it down to do the life things.

The story brings us back into the Shattered Planes about a year after Voidwalker and picks up a couple of new enemies - namely Daddy Antlers (who can kindly eat all the dicks) and a new immortal species that prey on Daeyari, the Aedari.

I loved watching Fi and Antal build their relationship further and for Antal to find his courage. Also having Antal still having all his house cat energy makes me stupidly happy.

Definitely a series I'd forever recommend picking up.

Thank you to S.A. MacLean for an early copy (and for accepting lil old me on your street team) and I'm currently in a quite carriage on a train but still want to shout my love for this book, I have left an honest review

Holy hell this was so good.

The politics, the drama, the fighting, Daddy antlers. This is one of my favourite books of all time.. I cannot wait for everyone ever to read this.

I am having an emotional crisis about the fact that it has ended, I may have to re-read immediately.

Did you read book one and go what if there was more fangs and tail stuff well here you go!!!

ever wondered what the perfect line between hot and evil - may I introduce Daddy Antlers.

This book was perfectly written and gave me everything I wanted (even if I wanted it to keep going forever)

Ill leave this quote here: "How do I say, put on your brakes, Gramps, in daeyari?"

Thank you so much to S.A. Maclean for the ARC on the street team and for Netgalley.

Thank you to S.A. MacLean for an early copy✨

If I could give this more than 5 stars, y'all know I would. My expectations for Sunsplitter were so high and to no ones surprise this has exceeded all of them.

From the expansive world that the author has created, the lore of the immortals to two (!!!) languages she's created, I cannot give enough praise. I laughed and I cried wayyy more than I would like to admit. Fi continued to be the same badass we know and love but learning more about Antal and watching him grow throughout the course of the book was deeply emotional. The new characters that we meet were such a delight and I am a little sad that we don't get more time with them.

I can't wait for y'all to read this one - truly.

And, for what its worth - she wasn't lying when she said we can't fix Daddy Antlers.

OMG THIS BOOK IS PURE PERFECTION
Books like this make me wish I could review more than 5 stars.

This book was an absolute emotional roller coaster. Laughing then crying within the span of about 5 pages?!??
The best writing style for a dual PoV I have ever seen, the slight changes in the narration to fit that character's behaviours was pure perfection.
I loved seeing Fi develop as a character and learning all the details about Antal's life. I loved the new characters we met, I just loved everything about it.

If you read Voidwalker, you MUST read this. If you didn't read Voidwalker, read it and then read this.
