House of Hearts by Skyla Ardnt:
 
Solving her best friend's murder means infiltrating a secret society, resisting a forbidden love, and running from a vengeful ghost in this sophomore novel by the author of Together We Rot.

Violet Harper knows her best friend was murdered. Even if everyone else has labeled her death a “freak accident,” Vi is sure she’d been trying to tell her something right before she died. Cryptic messages about her friend’s elite boarding school, her whirlwind romance, and the mysterious secret society she was entangled in all point to a more sinister fate.

So, Violet does what no one else seems willing to do: She transfers to the same fancy school to dig into the society’s murky history and find out what really happened to her friend. She knows the truth might not be pretty, but what she doesn’t bargain for is the handsome boy at the center of it all—Calvin Lockwell, the brother of her prime suspect and descendant of the school’s founder. He’s obnoxious and privileged, and Violet can’t deny their haunting attraction. It soon becomes clear his family is hiding a dark secret that may not be of this world, and suddenly Violet’s following her friend’s doomed footsteps down the rabbit hole. Even as details emerge of a deadly curse plaguing the school, she can’t escape her true feelings for Calvin. But loving him may be the last thing she ever does.
