This series was a welcome comeback to high fantasy after trudging through the Farseer trilogy. The first book is pretty good even though the glaring absence of the protagonist's girlfriend is a little odd initially. Of course by the second book you realize what's coming and the planned plot twist falls rather flat.
Some tips for the authors, when you want to make a character mysterious you either narrate their actions only to the readers or you make the other characters slightly suspicious of them. You don't make the characters simply refuse to answer direct questions and accusations, that just gets on the nerves.
The magic in the books seems to be purposefully doled out like the porridge in Oliver Twist's workhouse. The wizards seem too inconsistent with their powers and sometimes it feels like the authors used a deus ex machina.
Another odd thing is the choice of story segments the authors chose to relate in summary (traveling to the location of the dragon's eggs) or in a poem (ice wall). Its strange that situations ripe for some thrilling action and suspense were relegated to a couple of pages while much more was written about the dwarf's sea sickness.
Aside from these minor irritations the series is quite good to read and recommended to everyone.
