A new book is published over the internet in the form of a series of emails. “Those who order the book receive 98 e-mail messages during a three-week period from a sender identified as “e-mail mystery.” Readers are then treated to the voyeuristic experience of reading Sam’s correspondence. As the plot thicken and Sam’s life is threatened, e-mails arrive in a sudden flurry. Then, just when readers worry about Sam’s safety, they have to wait for an update.”
