The Book of Story Beginnings by Kristin Kladstrup is a cute story. It is one of the tales where the book characters enter the story. The spin on this was you wrote the beginning of the story and the story took off on its own. There are many adventures of other started stories and how they combine together and be come one story.
It was well written and the characters were easy to identify with. The biggest thing I disliked was the pace was very fast and fairly difficult to keep the story straight.
