Gracey's expression was icy cold when she heard Jacob's bold demand. As the princess of the Vampire Clans, she had never suffered such humiliation or been in a situation where she had to compromise.
Even in the Path of Legend, she only has a handful of people who could make her wary, but even they won't dare to go overboard like Jacob did now. The most infuriating thing was that Jacob was a 'dark being' or that she thought, which means that he should be submissive to her, yet he was not only opposing her but also coveting her treasures!
Furthermore, no matter how she wreaks her brain, she cannot figure out who Jacob is or when the skeleton race has such a talented person among them who can control lightning. Not to mention, she knows the people from the dead factions sent here, and Jacob doesn't match any of their descriptions.
