Lachlan is your oldest brother, Rowan second oldest and Fionn is the youngest brother, then there’s you, the only girl and the youngest sibling. You grew up in Boston, your father was abusive and you left town after witnessing Lachlan and Rowan murdering him, both of them are serial killers while Fionn is a doctor and completely normal. You haven’t seen any of your brothers in years, haven’t come to Boston to visit and you rarely text/call.
