(3.75 stars, but as a personal rule, I round down.) 
 One Night with a Prince was a really engrossing read. I was only a few pages in when I found myself getting swept away by the potent sexual tension between Byrne and Christabel. Damn. This book was hot as hell, I tell you. 
 The writing was great--as expected from Ms. Sabrina Jeffries--and the characters were likeable. Christabel's definitely my idea of an amazing heroine. Strong-willed, kick-ass, and fierce, she wasn't scared of fighting for what she wanted. I appreciated the fact that she did her best to resist Byrne--that she knew herself well enough to understand that Byrne and her want different things. Heck, if I was in her position I would have given in. Byrne was just so fucking sexy, goddammit. But the fact that she did do her best to say no to him made me respect her. 
 While I immediately took a shine to Christabel, I had a hard time liking Byrne. It's really hard not to compare him with Derek from Dreaming of You. You see, although they do have a lot of similarities, they differ in one important aspect: Derek tried his best to resist Sara, whereas Byrne selfishly pursued Christabel to slake his lust. And this annoyed me during the first few chapters. Don't get me wrong. I understand why Byrne was like that, and I do agree that he was merely acting consistent to how he was established in the story. But still, I find it difficult to appreciate a guy who's just interested in getting in your pants. 
 As the story went on, however, I started liking him. Especially when he realised his true feelings for Christabel. It's just that I wished that it happened sooner in the story, and not in the last couple of chapters. That made the romance less convincing. In the end, I can't honestly say that I believe in their love 100%. 
 Another issue I had is this: I'm not okay with the idea of Christabel and Byrne using sex to manipulate each other. Christabel did that twice, when she forced Byrne to admit that he was jealous, and when she forced him to tell her why she was "different from his other mistresses". Byrne, on the other hand, tried to seduce her so that she'd spill the beans about the letters. 
 Ugh. I'm sorry, but I don't think manipulation could ever be a part of a healthy relationship. 
 Overall, I really loved this story. I definitely recommend this for people who want a sexy, romantic read. 
 P.S. Yes, I know that his first name is Gavin, but seeing as he's called "Byrne" by most characters in the book, I thought that it's just fitting to follow suit.
