** spoiler alert ** 
 The first half is 4 stars, the second half is 2 stars, that makes 3 stars for the whole book. 
 The book is good overall, but the first half is twice better than the end. In fact, in order to appreaciate the second half, I had to read the two next books in the series, because the second half of the book is a bit of a nonsense to me. I'm glad I did read those 2 books because otherwise, I would have stopped loving the characters. 
 If you like fairytales, go for Kei's gift. The proud, gorgeous, extraordinary (like super-smart) talented, rich and powerful general physically enslaves the gorgeous, gentle and extraordinary (like super-powers) talented healer. But then, he is in turn willingly enslaved by his love of justice and his love for the gentle healer. 
 However, be warned, the end is a bit too sweet, I mean, too sweet for my tastes. I strongly advise those who find the second half of the book unsatisfying to go for the 2nd and 3rd books of the series.
