I bought the whole trilogy on rabid recommendations from the Amazon US site. I have to admit it didn't meet up to my expectations. It's not in the league of Raymond E. Feist's Magician as a first effort, nor even Robin Hobb's Liveship series. This is not a book to revise your standard of what is possible in this genre.
I do agree with most comments, concerning such points as a lack of editorial control, under-developed characters and the 'seamless' shifting of plot-lines (which I always find irritating - so few authors are able to do this well). However I do think the story to be an essentially good one and different enough to hold the attention. The very elemental nature of the created world and the resulting magical and religious systems are intriguing. Most importantly, the plot drawns you along and you want to know what is going to happen next.
The first part of the book is excellent and really builds up the anticipation for what is to follow. Unfortunately what follows is an interminable journey through the Root. The story does pick up again - but it's more a coasting along upon the established themes, with little or no variation on them. Drama turns into melodrama.
Rhapsody is built up into this incredible, gargantuan figure far too soon. You just know that there aren't going to be any problems that will give her too much trouble. And to be honest, I don't really find her character to be wholly sincere. Like the sword she wields, Daystar Clarion, she's extremely pretty to look at and extremely powerful. However, whereas a sword has a singular purpose, Rhapsody is unable to fathom her own goals and as such is portrayed as a sort of passive cypher for others to impose their will upon. Worse, she lacks an essential self-knowledge of exactly how incredibly potent a character she is and the myriad possibilities that are now open to her.
Achmed's reunification of the Firbolg is far too easy, quick and requires too much suspension of belief. Rhapsody could have played a far more pivotal part in this but is reduced from being a Joan of Arc character to Florence Nightingale.
The main 'threat' of the evil F'dor, Tsoltan and his nefarious plan of waking the World Serpent, the only part of the story that provided any real dramatic tension, is in the end, dealth with without any climatic struggle.
Like the reel of film at the end of the story, the story burns out and flaps around rather uselessly.
I can only hope things start to improve in the next book of the trilogy.
