Spending the summer with your girlfriend’s family is a big step, especially when your girlfriend’s grandmother is a dead witch who cheats at Words With Friends.

And in between lessons, Wednesday has plenty of ideas for torturing Kaitlyn--as long as Kaitlyn’s friend Jessie, and an old enemy of Wednesday’s grandma, don’t spoil their fun.
