The Queen of Hearts

The Blackthorn Academy is a private boarding college for the children of high society-heirs of corporate giants, European aristocratic families, politicians, and celebrities. Despite growing up in a single-parent household, Andrea Riley worked tirelessly to secure a coveted scholarship, earning her place at the academy with hopes of a brighter future. The academy's mission is to prepare its students for admission to the world's most prestigious universities, but the social environment among its students trains them for the harsh realities of life-realities the academy's leadership remains blissfully unaware of.
At Blackthorn, a student's social rank isn't determined by their family's influence or the number of zeroes in their bank account but by a high-stakes card game held at the start of every semester.
Andrea has no choice but to participate, as refusal means being automatically assigned the role of the class scapegoat. When she receives her role, however, she unintentionally captures the attention of the Sinclair brothers - heirs to a powerful arms manufacturing empire with operations frequently linked to the mafia.
Andrea didn't plan to let romance distract her from her studies and dreams of success, but everyone at The Blackthorn Academy knows damn good at least this one thing: when one of the "kings" wants something, he always gets it.
