This is meant to be mostly a book rec topic, but if people want to discuss how much "objectionable" material in a book is tolerable until the whole book is worthless, feel free.
Anyway, I used to be a voracious reader in childhood, but as I grew older, I became more and more frustrated by the lack of good contemporary fiction that isn't filled with curse words and/or includes all sorts of "obligatory sex scenes" that are completely unnecessary. So I haven't read adult fiction (as in written for adults, not x-rated) in a while. (Though in terms of kid-lit or YA, I did enjoy Harry Potter, and I enjoyed Twilight in an "unintentionally funny" way....but "Twilight" certainly shows that just because a book is "clean" in terms of no cursing or explicit sex, doesn't make it a good book!) Now, there's also a lot of good clean "classic" fiction from an earlier time (such as Jane Austen), and I guess I shouldn't reject a good book just because of one bad scene, but sometimes I would like to just pick up a book and read it without worrying about objectionable content. However, I find that reading a dust jacket or even flipping through a book before buying it isn't enough to weed all of it out.
So I'm asking for recs for good books that are clean, but I must admit, part me wonders if there really are books like that out there these days. Should I just give up and say "as long as it only has one or two bad scenes that I can skip over, a book is A-OK?" After all, even Raymond Arroyo recently recommended a book (about a cheating wife who schemes with her lover to kill her husband, based on a true story) with the disclaimer that "this is for mature audiences"...does "art" excuse such mature content?
