Overall I liked it a lot, but, <spoiler>the implication that I think they were getting at some sort of self punishment for an abortion when one of the characters was younger (maybe a miscarriage) because she found out her boyfriend was married? Not sure I perfectly understood that part...that I very much did not like.</spoiler> In a book that was largely affirming and about helping people to accept and stand up for themselves and find themselves etc etc, that sort lf passed by as a yup, thats just a fact lets never address it. 

Otherwise I loved it. Could have been a 4.5 or higher, but that one bit really knocked me out some because no one was like wait, that's not how that works.
