I bought this based on the broadly positive reviews on Amazon and was really very disappointed.
I'm an avid fantasy reader, having enjoyed the genre for years, but this stands out as one of the worst examples I've ever read. It has the feeling of being rushed, or lazily written; it lacks detail, there's very limited depth of character and no depth of plot.
I was left feeling it was a bad children's book - just over-simplified and under-thought. I remember reading DragonLance or Belgariad as a child; neither particularly challenging (being classic good vs evil), but both had great characters, interesting plots and a level of consideration that this book just lacks.
From the Mordecai's practically instantaneous 'discovery' of his power, which is frankly awful, to his rapid grasp of magic it's all just a bit simple and unbelievable. In a matter of weeks a self-taught magician is able to battle and defeat others who are obviously adept. Just because we're reading about magic and make-believe worlds, doesn't mean we give up all sense of logic.
I nearly stopped reading several times, but kept going in case things got better. They didn't. At least I was smart enough to only buy the first book and didn't waste any money on the rest of the trilogy.
So, give this book a wide berth, buy any of the awesome Fantasy available now and enjoy some decent writing.
