This book was so frustratingly lovable. As soon as I was introduced to Callum and Harper I immediately loved them both. As the story progressed I admired their determination, courage and how they never gave up even though they had so many reasons to. They were both their own strength and also their weakness in a good way and I was screaming in my head sometimes because I wanted them to stop being so stubborn and just tell the other they were in love with them. Towards the end I shed a few tears for Callum and Harper's ordeal that they went through and I was just so thankful they finally realised they couldn't live without each other and told each other they loved them. My only complaint is that I just wanted to keep reading the story and I never wanted it to end. I definitely love this book with all my heart!
