Stone Heart by Marie Robinson

My marriage will prevent a war, but my heart could ruin everything.
Brutal, massive, and as unforgiving as the hammer he wields, Commander Gideon “Stone Heart” Juraki is charged with delivering me to my indented. Peace for my lands depends upon my marriage to Lord Olsun, and I’ve resigned myself to it.
Captured by fae and forced to fight, I witness firsthand the ferocity of the man with an unyielding heart. A man who excites and challenges me in a way no other ever had before. A man who would lay down his life for me. A man as fascinating as he is forbidden.
Every victory brings Gideon and me closer to my intended.
Every victory, we fall deeper into the forbidden.
If I choose Gideon, I will ruin everything he has ever worked for.
If I marry Lord Olsun, I’ll save thousands of lives and break my heart.
Duty or love? I can’t have both.
