Parts of this book are a 5 star read and then other parts drag it down so much. 

The relationship between Sharon and Mel was the most interesting part of it, and there's a few big plot twists/reveals that alter and shake up that friendship and it's great, until there's one plot twist too many and the story goes from interesting to overly dramatic and then just plain uninteresting. I also personally really hated the last big twist, it feels wrong even calling it that as it's a trope that I don't have any time for. The fact that Sharon becomes more and more unlikable as the story goes on makes it even harder to care after this thing happens. And I don't have a problem with unlikeable main characters but Sharon feels extremely passive for so much of this story, and that's where it gets annoying.

I would definitely read more from this author because, as I said, there were parts of this book were great and had me fully immersed in the world of these two characters, but it felt like every time it was getting into a rhythm and really captivating me, she'd throw in another life changing plot point and everything good that had been building fell apart. 

As for the end....

Was Mel in love with Sharon, like properly in love with her? I got that impression from things other people were saying but it felt unclear when Sharon was talking about it. It probably makes it even worse if that is what was happening, and I'd rather have read it all from Mel's POV if that was the case, and see her complete that last project and leave Sharon. Honestly I think I'd rather have read that anyway
