What the author does fabulously is make you buy into the beauty and solidity of the relationship. So when things fall apart, your heart falls right along with it. The plot and story is so simple, straightforward and realistic. Maybe that's what makes this book hit home...it is something that could happen in our own lives. Although there was resolution of sorts at the end, I have to admit to just feeling depressed. I was tempted to only give four stars, but anything less than five would be a lie.
One side note, it has been tagged BDSM, yet there's not a single BDSM moment. Erotic, yes. BDSM, uh, no.
