The picture book is for school aged children and older people.

 It is not horror, but I think this belongs to a jenre of ironical comedy.

The story about the two skeletons, Skinny and Garry, who want to be a human being.

They happen to know that humans are having a dance party that night. 

So they are going with their special human-face masks.  

They come to the party and try to find their new human friends.

As Mr.Skinny finds a girl friend first, Ms. Garry  wants to have a good-looking partner to dance with her.

WOW!! It is so bad! The Garry's beautiful mask flew away.

The human friends run away and the skeletons have no way but coming back home.

However, they are very happy as their old friends waiting for them at home.
