Pet's Revenge (Edgar and Ellen)

This is my favorite book of the series so far. I wasn't a fan at the beginning but I'm glad I stuck it out because this book is good.

These read especially easy for YA lit. But the story is a great reflection for an adult. You can see just how sneaky these twins are and appreciate the trouble they get into. The morals learned are equally important for children, though.

Pet is a one-eyed hairy thing that Edgar & Ellen torment as a means of "play". But Pet has been up & into to something in the lab..... All of a sudden Edgar is behaving oddly and Ellen wants Edgar to return to his old nasty self.....
