Baldr's Secret Mate. Mated to the Viking Alpha, #3

The mage trapped by a magical shield has been my best friend for nearly a decade. But he doesn't know his destiny is to kill my family. Or that he's my mate. BaldrI met Mist the day he arrived in Fenris. It's hard to ignore magic like his when I thought I was the only mage in town. We became fast friends and it wasn't long before I realized he was my mate. But he's being held captive by the enemy, and tortured so that he can be used as a weapon against me and my family.
I want to be with him, to tell him I love him. But I've seen the future and my visions are never wrong. Mist will be the one that gets me killed. Mist I've been trapped in this magical bubble for almost a decade. Stolen from a home I can barely remember and tortured by a crazy werewolf to do his dirty work, I'm all alone in this world. Except for my best friend, Baldr, who makes it all tolerable. Being a witch too, he understands me on a level nobody else can.
But recently I've been realizing how much I care for him. In fact, I think I love him. I'm not sure if it's because I don't know anything else or because he's actually the guy for me. All I know is that I don't want to ruin our friendship. If he leaves, I'll be all alone again. However, I'm a danger to him. I still can't control my magic and it's only a matter of time before it consumes me. When that happens, I want him as far away as possible.
