Entertaining, but I'm not sure if it is worth all the hype it has gotten. Reading this only whetted my appetite for more Inheritance books. Based on how this one goes, I'm fairly confident we'll see more adventures, but this was more of an appetizer than a main course.
Of the three short stories included, the third is by far the best of the lot. Better yet, it builds on existing lore and really brings home some of the assertions about the Urgals.
