Talasyn and Alaric are at opposite ends of the Hurrican wars. Talasyn is the last lightweaver after the purge on the continent. Whereas Alaric is the shadowforged heir of the shadow kingdom.
As Talasyn prepares to be dropped into enemy territory to seek the light sever and understand what is drawing her into the abyss, Alaric is preparing to meet his match. Both Alaric and Talasyn unwitting becomes involved in much wider politics between the different nations, in the name of harmony.

This is a slow paced fantasy focused on world building, and backstories. There are quite a few technical details to get your head around, especially the first 50 pages; these all serve its purpose for the rest of the story. So it's a book which requires attention, rather than scanning and skipping.

I liked the descriptions of the Wasp, Coracle, Aetherspace, simular to Iron widows by Chloe Gong.

"Do you make it a habit to compliment everyone you try to kill?"
This is a enemy to lovers trope, marriage of convinence and politics. There are some laugh out moments as the two awkwardly flirt, catch the feels

"I don't belong here. I don't belong anywhere"
Both are battered and bruised from early abandonment. There are many moments where tentative bonds begin to be explored...

I think there is a a lot of potential for prequels (esp as the second book is coming out in Dec 24), to focus on the cataclysm which happened 19 years ago, and the run up to it.

Based on mythology from the Philippines, Thea Guanzon has done an amazing job of creating a world which slowly drew me in, and connected me with Talasyn and Alaric.
