The initial Runelords quartet was innovative, had pulse racing action, an interesting magic system which raised profound ethical questions and a somewhat disappointing ending, that left far too many questions unanswered and plot threads shorn.
In continuing this series, David Farland corrects many of the problems that his last book created. The characterisation is still patchy, but as ever his description of the hero is detailed and nuanced, as Fallion fights to control the power within him.
I would encourage anyone who was disappointed by the conclusion to the first set of Runelord books to persevere with Sons of the Oak, as when the series is viewed as a whole the plotting feels less rushed, and more epic, without having to pad huge sections of the book with a trip to Rivendell/the One Tree or descriptions of characters pulling their hair.
