A Perfect Mess (Hope Parish Novels Book 1) by Zoe Dawson
I know what you did last summer.
Aubree Walker, the perfect girl most likely to succeed, is sure there’s only one person who knows what she did.
Booker Outlaw, one of the three Outlaw brothers–all identical, all gorgeous, all from the wrong side of the tracks, and all pure bad boys. He was always the unpredictable one, the one who would be brash enough to make it big self-publishing horror novels on the internet. He promised never to tell, but everyone knows you can never trust an Outlaw.
Then a year later, in the middle of the night, she receives a phone call at Tulane. Her aunt, who took her in after her mother’s death, is in a coma under suspicious circumstances. Now she has to face that one person who knows all about what she did that summer–sexy Booker.
