I loved the Three Worlds series and was enthusiastic to pick up Ian Irvine's next offering. His style is undoubtedly an unusual one and can take some getting used to, but in those books it works wonderfully. Unfortunately, Vengeance seemed to magnify many of the more uncomfortable aspects of his writing while lacking most of the redeeming qualities present elsewhere. The story-line was rushed, containing several frankly sloppy plot-holes and implausible happenings, while characters often felt thin or undeveloped - I initially thought this novel must have been written a long time before the other books or written for a much younger audience. Given how much I would recommend the other novels by Ian Irvine it pains me to say that the whole thing felt disjointed and half-formed, making me wish it had been through several more revisions, especially as I would have always said that his careful attention to detail was one of Ian Irvine's strengths. Many of the same elements were present from the Three Worlds sequence - a capable female protagonist struggling with her unusual abilities, thrown into difficult situations with unfortunate twists of fate or outside events turning victories upside down - but the delivery was noticeably poorer and the novel suffers as a result of the inevitable comparisons the similarities invite.
Disappointing, and I don't think I'll be continuing with this series.
