Goodreads reviews:

"The writing is beautiful, the characters complicated, the plot brimming with adventure and political intrigue. Masterfully weaving together multiple POVs, Sienna Frost unflinchingly explores the darker aspects of human nature, the complexity of interpersonal relationships and the brutal, agonizing choices they are forced to make for love, honor, and loyalty. True to most pre-modern societies, the characters are often forced by fate, birth, and other external powers to disregard their personal desires and attachments for the sake of survival or duty. Even some of the more "villainous" characters force the reader to question their own preconceived notions of good or bad, right or wrong. There is no one is this book who can genuinely be called "the good guy." All of the characters are flawed, all the relationships fraught, all of the conflicts too nuanced to easily pick sides. I highly recommend it to anyone in search of a fantasy novel as deep and thought-provoking as it is thrilling." - J.L. Robertson.

"This is the kind of story that, for many reasons, pulls you in and doesn't let you go. There's something almost relentless about the way things (many of them dark and difficult) just continue to happen to characters- complicated, interesting characters- who have to roll with the punches no matter what."- Juniper

"I've had my beliefs exposed, challenged, subverted, and then destroyed. I think if I had to describe this book in one word, it'd be 'visceral.' " - Isianya

"Obsidian is about humanity with all its flaws told in the kind of beautiful prose that pulls you in and holds you captive, teasing with every twist as you excitedly turn the page until the very last nail-biting line. " - Alora Pendrak

"a tour de force of dark, gritty fantasy that takes the multiple POV method and a cast of flawed, fascinating, and complex characters to a whole new level of engrossing reading." - Kyle A.

"Complex characters with interwoven backstories that struggle towards impossible goals in a truly breathtaking world. " - Gabby Wright

"One of my favourites ever, one of the best epic books I've read. If you are looking for a well written novel, with a great plot, full of interesting MC, each one with a story as interesting as the previous one. This is a "must". I couldn't drop it for 3 days straight" - Vastenerada
