Gwen is the princess of England who leads a determinedly routine-centered life whenever she is not pining for England's only female-knight. She also happens to be betrothed to Arthur, who spends as much of his time as he can escaping from his responsibilities as he can. The two have been betrothed since birth and just so happen to hate each others guts. When they discover that they have more in common than they think, they band together in a fake relationship in order to avoid detection and perhaps find love with other people along the way.

The characters are the best part of this novel. There are many other good parts but the characters really are the best. The development they experience, the relationships they have with each other. Arthur and Gwen's slowly growing friendship, Gabriel and Gwen's sibling devotion, Arthur and Sidney's loyalty to each other -- it's all great. And Bridget? I adore Bridget. I think the dual perspective of the novel really added to why I loved the book so much. 

The world building is of great quality. The way in which Arthurian legend was incorporated into the world in which the characters lived and the impact it had on the plot was masterful and I really enjoyed it. I read the texts, translated, when I was around ten but haven't experienced any of the modern adaptations, but this book definitely made me want to. 

Despite the fact that there is so much going on, it never felt underdeveloped or hurried. Things took enough time and had proportional consequences. 

This book is also funny but not so much as to devalue it's message or make you take the plot less seriously? It's just great. And the romances are just so charming, I was cheering for them the entire time.  

In conclusion, please read it! It's a great book that makes you feel as though you're filled with light from the inside despite there being a generous amount of quite serious events.
