What "Wiz" Zumwalt could do with computers was magic on Earth. Then, one day the master computer hacker is called to a different world to help fight an evil known as the "Dark League".

Cook was in the process of writing book 6 of this series (The Wizardry Capitalized), in spring 2000, when emergency heart surgery, and subsequent medication, interrupted him [1]. The novel remains uncompleted, and Cook asked for input on his blog site as to whether or not he should publish the unfinished work. In February 2008 he announced that he has decided to present the unfinished work online.[2]
