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.

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.

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.
