Violet was never an easy child growing up, constantly pushing the boundaries and seeing just how far she could go before those around her snap. She never really had a dominant figure to keep her in line, she never wanted one. When Tristan makes an appearance in her life, she isn't really given a choice.
Tristan was the embodiment of confidence, he radiated it and attracted women like moths to a flame. When he sets his eyes on Violet and she doesn't immediately swoon after him like all the girls before her, he becomes intrigued and sets out to make her his.
Violet won't submit without a fight.
