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...)
Besides the trope ("show me how this sex thing works, so that I can be with other guys - but uuuups, while doing that we will fall in love for sure"), I really didn't like how callous the heroine uses her brothers best friend, not for one second thinking about what this could do to him (he has a sad back story about his family and is more a brother than a friend, which also makes it ewwwww if you look at it closely...). She basically blackmails him into doing sexual stuff with her with the old "either you do it, or the first guy I meet and be it a known rapist and bully..." - I don't like her at all.
What irks me about the writing: I suppose this is supposed to take place in the US, as the hero is applying for a scholarship to go to England. But the vocabulary used is a strange mix of British and American (e.g. "bloke", "bloody" etc., but "TV" instead of "telly") so there is some confusing sense of this being an English book, while never sure about the location.
So DNF for me. Which is a pity as Jack did have potential, as did Matt, the brother.
