The second chapter of best-selling author Laurell K. Hamilton’s thriller begins here! Vampire hunter Anita Blake has crossed the paths of the worst St. Louis has to offer--and now they want her out of the picture for good. But Anita isn’t the type of person to go down without a fight…and she’s going to make sure it hurts something fierce. Find out why Comic Bulletin calls the ANITA BLAKE series “Sexy…with a wicked sense of humor.”
As the variant cover states in the fine print, Wolverine's appearance is cover only and in fact, this series is not even a Marvel property and takes place in its own universe so an actual crossover couldn't happen canonically.
Irving Griswold's appearance is off-panel, he and Anita have a discussion over the phone and although all the dialog is shown, Irving isn't depicted in the issue.
