I expected it to be at almost the same level as Jordan's WheelOfTime or Martin's SongOfIceAndFire (which are my -unreachable- top standard fantasy series). Unfortunately I was highly disappointed by Rhapsody.
The story is interesting, the book is enjoyable, but...
...some events are hardly credible or at least unlikely, some others just take a time too short to happen (I'm thinking of Achmed ascent among the Firbolg), or use superficial solutions.
Some situations are worked out in simplistic ways with deus ex machina stratagems.
Rhapsody is an absolutely unlikely character, not because of her magical characteristics (I like them very much), but because of her nature. She is TOO beautiful, TOO kind, TOO (impossibly) unaware of the fact that every man who gets a look at her is struck by lust and passion, TOO naive and innocent: wasn't she a prostitute before escaping from the Lost Island? How can she rouse EVERY man interest without being aware of it? I would find it acceptable if she attracted men unwillingly but at least consciously! A woman so intelligent and persipacious cannot possibly be so ignorant of her effect on men, especially since it has been happening tens of times!
She is the personification of every feminine quality: strong but kind, sensual but innocent, stubborn but gracefully feminine... She is TOO perfect, maybe it' s just envy (!!!) but I don't like her!
I can't fully understand nor explain the reasons why I'm not satisfied with this book. In truth it's quite good and enjoyable, but... Rhapsody is too much of a heroine, she never falters, she always works out the situation in the most correct way. But this is not realistic!
I think I'll buy the next books of the series, because at the moment there isn't a satisfying offer of good fantasy, so I suppose you too can buy them, but if you have not read Jordan and Martin yet, I suggest to choose them instead.
