I'm usually sent to kill someone, now I'm being sent to protect them instead. I just didn't plan on him to be mate and he didn't plan on me being so feisty. Emma is a twenty year old assassin and Tristan is the alpha of all alphas. Someone wants him dead and she's sent to protect him but he can't know that. She's feisty, stubborn, doesn't play well with others and gets under his skin like nobody else. He's persistent, aggressive, moody, he annoys her to no end and is determined to make her his.
