I used to LOVE L.J. Smith ! 
 I remember I read this book at least twice and I really liked Julian so much ... but if you think about it he was actually a massive asshole, some creepy stalker man ... like he kidnaps Jenny and her friends to some dangerous place (view spoiler)[and then lets them think that one of them is dead for a whole book or more ! (hide spoiler)] Like all the details of him are blurry tbh but yeah, what I remember is : creepy. 
 I never liked Tom because honestly he seemed a bit shit too ... didn't he make her dress a certain way or something like ... RUDE ! 
 I don't remember much else except the fact that the premise was interesting, at least of the first book, wow ! I liked the women of the story if I remember right too. Just the men were not good and they were still supposed to be seen as kinda ideal ... nooo why is this such a pattern in YA !
