The Blue Eye: Book Review

I read a book called “The Blue Eye”.
The main characters were Biff and her sister.
They were helping their mom tidying up, and they found their dad’s toy box.
There were beautiful marbles so they kept them. After they backed their room, their magic key grew and they arrived at town.
They saw a woman was running away from some guys.
She threw one big blue stone from the window and ran away.
They got it and followed them.
When they finally found a woman, it was dead end.
So Biff threw all the marbles he had and get bad guys away.
A woman called an airplane and took them to the palace.
She was a princess!
And she needed that blue stone to be a princess!!
Everyone thanked Biff and his sister and they gave them great dinner.
