Fifteen-year-old Roberta wakes up in a hospital after the incident which turned many of her classmates into zombies, only to be told that her mother is dead and all of Scotland has been quarantined--but something suspicious is going on and it is up to Bobbie to figure out what it is.

In this adventure Tank the Great Dane's active imagination takes her and Haggis the Scotty on a airplane trip to Scotland, where they visit a castle, enjoy high tea--and get chased by a werewolf.
