Technically the writing was good & storyline was unique but the overall romance lacked depth & the emotional tone was boring. Maybe that's why I didn't really care much for the main characters. Heroine was a coward & dropped Hero at the slightest challenge. I didn't feel her angst re: why she had to leave him nor did I feel her missing Hero. Basically she was emotionally superficial. She was good at looking calm & collected & wanted to stay that way emotionally. Hero had a way to shaking her out of her desired emotional deadness. I don't see her appeal & don't understand Hero still holding a torch for her (he stayed celibate during their time apart) with the way she abandoned him. I think he knew deep down inside that heroine was not emotionally strong & thus his choice to keep the nature of his job from her until they married. The storyline was actually pretty good but the writing lacked the accompanying emotional intensity to make this a poignant read.
