The Day the Mustache Took Over by Alan Katz

The Day the Mustache Took Over is a preview copy from NetGalley.

This book is about two kids named David and Nathan who have parents who are always going on business trips, so they need a nanny. Nathan and David aren't very good kids, so every time they get a nanny, they always scare her away.  The next nanny they find is actually a Manny!  When they first meet him, he seems like a goody two shoes, but once the parents leave, he ends up being not so good after all.  He likes being crazy and he doesn't think the boys should have to go to school.  But the boys think something weird is going on with him.  David suspects he might be a spy!  What is going to happen???

I liked this book because, at first, the boys seem like they are really bad kids, but once the nanny comes, they turn good.  They are always doing their homework as soon as they come home from school and they are cleaning the house when they make a mess.  It seems like that the kids are the good ones and the nanny is the one that is always breaking stuff and making a mess.  I liked that this book was a funny mystery, as the boys tried to find out who the nanny really was.
