November 22, 2016 debut

Betrothed since childhood to the prince of Mynaria, Princess Dennaleia has always known what her future holds. Her marriage will seal the alliance between Mynaria and her homeland, protecting her people from other hostile kingdoms. But Denna has a secret. She possesses an Affinity for fire—a dangerous gift for the future queen of a land where magic is forbidden.

Now Denna has to learn the ways of her new kingdom while trying to hide her growing magic. To make matters worse, she must learn to ride Mynaria’s formidable warhorses before her coronation—and her teacher is the person who intimidates her most, the prickly and unconventional Princess Amaranthine, sister of her betrothed.

When a shocking assassination leaves the kingdom reeling, Mare and Denna reluctantly join forces to search for the culprit. As the two work together, they discover there is more to one another than they thought—and soon their friendship is threatening to blossom into something more.

But with dangerous conflict brewing that makes the alliance more important than ever, acting on their feelings could be deadly. Forced to choose between their duty and their hearts, Mare and Denna must find a way to save their kingdoms—and each other.

"Dennaleia and Amaranthine’s narratives combine to create a powerful and exquisite love story that also provides incisive political commentary and cautions against zealotry, vengeance, and intolerance. The central mystery is intriguing, Coulthurst’s worldbuilding is excellent, and the book’s explosive conclusion both thrills and satisfies."

My review: Oh, my heart! This book! My heart! I love this book so much. It's intriguing fantasy with magic and politics and ponies, all wrapped around a ridiculously satisfying slow-burn romance between two fantastic characters. The world feels realistic and lived-in, with just the right amount of world-building detail to make it easy to follow all the political strains and alliances and dangers. 

I especially love the magic--it feels small and subtle at first, a little thing that hardly seems worth all the fuss various political/religious groups are making over it, but then... it isn't so small and subtle anymore, for reasons which I shall not divulge because SPOILERS, and then all at once this world's magic is terrifying. AND I LOVE IT.

But most of all what I adore about this book are the main characters, Denna and Mare, and their relationship. It's such a delight to watch these two young women who are very different people from very different lines, with very different sets of expectations and burdens on them, slowly come to like and appreciate each other, to see each other's strengths and flaws clearly, and to work together when all kinds of forces are trying to push them apart--and, of course, to fall in love, which happens so naturally and so perfectly I barely even noticed when I shifted from "aw you'll like each other eventually" to shouting JUST KISS ALREADY at the book every three pages. And sometimes I would mix it up and shout NO REALLY YOU LIVE IN A VERY DANGEROUS WORLD JUST KISS ALREADY.

So, yes, it's the kind of book that had more shouting a lot because I was REALLY VERY CONCERNED for these characters and their dangerous, magical world, right up until the end when I wasn't shouting anymore but sighing a deep sigh of happy satisfaction, because literally every single thing about this book is fantastic. Including the horses. I love it.
