The girl you know

"The week before Luna's twin sister Solina was supposed to head back for her final semester at Kingswood Academy, an elite boarding school in the Washington mountains, she told Luna she was dropping out. When Luna refused to let her throw away her future, Solina disappeared. Twelve hours later, she was dead. Luna knows Solina's death wasn't an accident, even if the police say otherwise. There's a reason Solina didn't want to go back to Kingswood, and Luna knows she'll find the truth there. All she has to do is become Solina. Playing Solina comes easy, but finding answers is far from it. Between the cunning, cruel people Solina called her friends, Luna's budding feelings for her roommate Claudia, and the harsh realization that Solina had dark secrets, getting to the bottom of her sister's murder is more difficult than Luna could have ever anticipated. But when you have nothing left to lose, you're willing to do anything to get what you want. There's no limit to how far Luna will go to avenge her sister - even if she has to burn all of Kingswood to the ground"--
