I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
I really immensely dislike Perry, the first-person narrator and heroine.
She is jealous of her baby sister who is skinny and pretty and popular and already working on a career (fashion blog, whatever).
She lets her 15 year old sister get drunk with a group of untrustworthy people on a beach, lets her alone there to go for a walk and her only thought is that the guy her sister is "slobbering on" is unworthy and totally unattractive - she sounds like a sanctimonious asshole.
She doesn't want her little sister to be happy, says "as always it rubs me the wrong way, when Ada has a great time".
WTF is wrong with you???
I have a baby sister myself. And I really don't see any chance that this "heroine" is redeemable for me.
