Dragon’s Dawn by Sam Burns

For nineteen years, I have carved myself into a dutiful son, a courtier of unimpeachable wit, and a genuine delight at a tea party. Now that my success in society has planted me in the path of Mikhail Vasiliev, it’s clear I’d have been better off keeping my head down.
Prince Mikhail is the second son of a traitor. Third in line to the throne, he has a reputation for violence, debauchery, and being a thorn in the side of his cousin, King Dmitri. That is, until the king decides to get him out of the way—by marrying him off.
To me.
Suddenly prince of a brutal, frozen land, I have no choice but to spy on my father’s behalf. From the morning of our wedding, my beastly husband and I have been at odds, but if I cannot win him over, I’ll find myself in the jaws of his colossal red dragon.
By the time I realize there is more between us than hostility and mistrust, it is too late. The die has been cast, the knife thrust, and our private battle is set to topple the whole kingdom.
