I'm probably rounding down from 3.5. Well done, it's just how much you connect with the main character, who narrates the entire book. She's a high-femme, horny, wine abusing, dramatic, self-absorbed, Bridget Jones type, lesbian who comes with a basket of issues. Around the halfway point the book turns and the character starts to "find herself" and it gets self-helpesque.
I almost didn't read past the first ten pages because of the voice. Pushed past it. Identified with a few of the issues the mc had, and that kept me going. Not likely to reread, and probably won't recommend to anyone I know, but if that sounds like a character you would like or identify with, you should definitely read. Most likely if you are similar to the character, you'd never admit it and thus miss out on this book.
