Yancey, Rick Alfred Kropp: The Thirteenth Skull, 297 p. Bloomsbury, 2008. Alfred is off on death-defying adventure again. This time, not only the Company is after him. Someone new is after Alfred's head and after revenge. Yeah - finally Alfred has received the book covers that he deserves. I want to throw away my old copies of the previous titles and get all new ones! Is this book intricate and thought-provoking? Not really. The action is fast and furious and the danger is palpable. No heavy thinking required, but your nerves had better be fortified! MS - ADVISABLE. Cindy - Library-Teacher.
