The fourth installment in the "Rook" series, Snowman finds Jim Rook coming to the aid of an Uniut college student in his class. The story manages to wind in some of the Uniut (read Eskimo) culture and superstitions into the modern-day world, and Graham does what he always does - keeps the reader on the edge of the seat. Mr. Rook has a wry wit, and his ability to see the paranormal allows him to function in our world, observe beings in several others, and keep his own life on an even keel, even allowing a romantic interest to peek it's head around the corner. Superbly written, with constant action and suspense. To my disadvantage, I picked this read up at the local library, not being familiar, and also not realizing it was the fourth in a series. I am about to make a beeline back, to search out the first three. You should too.
