Blood Beneath the Snow by Alexandra Kennington

A heart-pounding romantasy following a rebellious princess who must compete to the death against her siblings for the crown to ensure justice, while fighting her feelings for her country’s most powerful enemy by debut author Alexandra Kennington

Revna is no stranger to struggle. As the only member of the royal family without a magical ability, she is seen as an embarrassing mistake by her kingdom and a blight on her bloodline. Luckily, Revna has found family in other outcasts in her kingdom. But when her two closest friends’ lives are put in danger, she is determined to save them by any means necessary, no matter the cost. The Bloodshed Trials—a competition where the last sibling in the royal family standing takes the throne—might just be the ultimate price.
Revna turns down her arranged marriage and commits to competing for the throne only to be kidnapped by the mysterious and terrifyingly powerful Hellbringer, the general of her country’s greatest enemy. He has the ability to rend souls with the flick of his wrist and is every inch as intimidating as the war stories say he is. But Revna wonders if there may be some humanity left in him—especially when he reveals there are other parties who want her on the throne for their own secret reasons.
