This was not bad, but the book had serious plot holes and, therefore, needs fine-tuning. I had no problems with the characters because they were genuine, well-written, and authentic; however, the story was a very slow burn, which I loved, but the switch from 'hate' to love was so fast and ridiculous that it destroyed the reading experience for me.
I couldn't wrap my mind around Slade's behaviour thoughout nearly the whole book and his sudden mood switch that we are supposed to believe because of a few diary entries. Don't get me wrong, the slow burn was so good at the beginning, and I was in love with the letters both of them exchanged since childhood that we got to read between every chapter.
Still, the ending destroyed almost everything for me, mainly because of the implausible and unnecessary plot twist. What was that, and why did we need this kind of thing? I mean, I love drama, but the drama was life-threatening and still over in just one or two chapters, and that made it a tiny bit ridiculous.
Despite all, I wouldn't say that I didn't enjoy reading this book. I had fun with it for the first half, so I rated it with an average three-star rating. It was okay and not the worst book I have read. Believe me, half of this book is enjoyable, and I adore Slade's mother.
