The answer is yes. Two women can absolutely be too close. In fact, unless they are sleeping together, they should establish distance right away, distance is good, it gives one perspective and space. This proved to be surprisingly exciting. Exciting is generally what you would expect from a thriller, but there has been too many of too similar of these books lately to really go into reading them with high expectations. This book, though, absolutely delivered. It promised to be dark and really went there. Not quite a traditional genre work, the body count is off, the chapters alternate more organically, it doesn’t quite twist and turns in a way these things normally do, this was much more along the lines of dark psychological drama centering on the subject of female friendships. Toxic and otherwise, but, of course, mostly toxic, because it makes for a more fun story. The main protagonist is Connie, a thoroughly prototypical suburban yummy mummy with a nice life, one man, two kids, etc. Maybe slightly lonely. But then one day she meets another yummy mummy in the park, the woman who has just conveniently bought a place right down the street with her wife and their two kids, friendship sparks go off like fireworks and from then one Ness and Connie are inseparable. Fast forward six years and Connie is locked up in a loony bin, severely messed up physically and mentally, with only a well meaning shrink named Emma determined to unravel the puzzles tangled up in Connie’s dissociative amnesia ridden mind. We’re clued in that Connie’s done something terrible, but it’s going to take time to find out what and meanwhile her madness undeterred charisma and character draw Emma in entirely too much and her own professional and personal life get affected and confused by association. So it’s essentially a story of boundaries in female relationships on various levels, the way they seem to be impossible to maintain as the personal involvement progresses. It’s messy, it’s complicated, it’s…it’s kind of fascinating, in that train wreck way. All the main characters in this story are married people of a certain social class/status struggling with their individual challenges and dissatisfactions, none of their relationships are quite functional or happy, with possible exception of Connie’s elderly parents. This book says a lot about marriage and almost none of it is positive or promising, but it’s certainly compelling to read about. In fact, this book really drew me in. I remember thinking…wow, this must be what women’s fiction can be when done right. Because, you know, usually it’s complete sh*te. And then there was that omnia vincit amor ending as incongruous as Jeff Bezos in Walmart, the people pleasing female pandering estrogen infused happy ending the book didn’t need and shouldn’t have had. After all the heavy subject discussed, struggles with mental soundness, addictions/dependencies, marriage, motherhood, friendships, etc. you’d think this book would deliver an appropriately dark doozy of a finale, alas, the author went at it sunny side up. I can understand the choice, but…it wasn’t ideal. It did dampen the overall effect somewhat, but otherwise this was really fun, so I'll be uncharacteristically generous for once. Thoroughly engaging well written and relatively quick trip down the uncharted territories of the psychological darkness. Recommended.
