I read this book and its sequel as well. I really enjoyed both. It has some of Feist's standard elements: young male hero, crisis, his growth as he faces challenges including dealing with his past. It's a tad different than the SerpentWar Saga in one regard. This new series involves more intrigue, covert dealings, etc. The events very much fit the series name, things happen more in the shadows.
If you enjoyed the RiftWar saga, Legends of the RiftWar works, or the SerpentWar saga, I'd really recommend this book. I definitely find it a substantial improvement over the Krondor series.
