For me, it's more like a 3.5! I truly relished the deranged and codependent relationship that these two women shared. It was this kind of passionate possession they had over one another. I thought they were well-developed, three-dimensional women. Although the plot did seem to have some lulls at times, the tension between Monica and Sheila was sufficient to draw me in. Moreover, the way art was discussed in this book didn't veer towards the cliché. In fact, it's probably the only instance where I've enjoyed the subject of art from an artist character within a fictional novel. Overall, I adored how suggestive the language was, bordering on the erotic, yet not being cringe-worthy. However, the ending felt hasty, with the addition of a plot point that seemed completely unnecessary and detracted from the book. But that last line......is definitely something that will be lodged in my mind for a while. "You shouldn't have done this— you shouldn't have doubted me— we'll be friends for a long, long time— unless one of us dies."
