Query: Almost as good as Bestiary

I picked up Vigil after reading in the back of Bestiary that a character is a continuation, but you don't need to read one before the other. Both books are stand-alone and are enjoyable. Vigil starts off like all thrillers - hits you over the head with a hammer of suspense - then, like all thrillers, sort of slows down to get into the plot. There are several missed branches that the story can take (don't get too tied up into the fact that there is 'something' in the basement of the science building, as that peters out after its mentioning.) Still, enjoyable to read.
