It all started with losing her mother, getting thrown into a boarding school, and then having the rumored witch-like princess of the kingdom desire her and want her by all means necessary. But it isn't the innocent type of desire she had expected. It's something much darker than she could ever handle. **** Sera didn't think her life would ever take a turn for the worst until her worthless father remarried her mother's half sister and, on her orders, sent Sera to a boarding school that was far off in a different kingdom—Elysium High, an all-girls academy for the most prestigious daughters in all of the seven kingdoms. In Elysium, only the most powerful could survive, as even the prettiest and most innocent-looking faces had skeletons in their closests and would ruin anyone or anything that got in their way. Unfortunately for innocent and naive Sera, she would become the newest prey of Elysium, and everyone wants a piece of the beautiful redhead. But what happens when the most unexpected person also takes an interest in her?Electra's name alone was enough to get the entire school shaking in fear. Not only was she the only heir to the most powerful kingdom in the realm, she was also known as the cold-hearted queen of Elysium High. Nothing and no one ever caught Electra's attention, until the arrival of Sera, where everything changed. And all it took was for clumsy Sera to bump into the most powerful one of them all.
