In "The Watcher", we follow a very grumpy ghost who does not like the fact that he now has a new roommate. He would have been perfectly happy in living out the rest of eternity on his own, but she had to walk through the door and ruin everything.
In "Unknowing Revenge", Mia and her cat companion, Whisk discover that they not only have garden gnomes for guardians but the giant boa constrictor that just slithered in like it owns the place is supposedly going to keep them all safe, or is he?
