I loved Deeper -- and Harder is almost as good. BTW, the titles may seem crude, but they actually relate very well to the themes of Caroline and West's relationship, as York makes clear. So hold your assumptions about these books and these characters. York will shake them up (in a good way). Both characters change so much over the long course of the two books and their long relationship. York makes that credible and moving, even without a lot of other plot going on. That's the only reason I prefer Deeper over Harder, in fact. The first book has more plot. The second book is crucial to the story, to the longer narrative arc, but it's slower going. I'm not sure, even, if they wouldn't have been better off as one condensed book? But these are quibbles -- both books are great reads.
