While Princesses Sleep, Princess Book Set (Princess Castle Adventure & Mystery Series, Books 1-4):

While Princesses Sleep: Princesses of Chadwick Castle Adventure, Book 1 (Princess Castle Adventure Mystery series) is a tale of two princess sisters living in an English castle in the 19th century. 
Synopsis: 
Princess Elle has discovered a mystery and drags her sister Princess Belle on an adventure. The princesses search the English castle they live in this short story for children. This princess adventure storybook features over fifty full-color illustrations from master artists carefully selected for children. Children will enjoy this castle adventure in this first book of the princess books series. 
Great for readers who love Cinderella type fairy tales and English princess stories. 
Details: 
This adventure storybook diaries their adventures and culminates in Book 8. While Princesses Sleep opens with Princess Elle discovering a strange sound in the night. Curious, she determines the reason for these mysterious noises and starts the adventure with her sister, Belle. Something is afoot at the castle and they must find out what this is. However, finding the truth behind the secrets they stumble upon leads them to strange answers? What sort of trouble will the princesses get themselves into? 
This children's illustrated story is written from a first person point of view and is similar to a princess diary type book. In the princesses' adventure, they are also introduced to the world of ballet. The spin-off series (coming soon) will deal more with ballerinas and ballet stories. 

Each full-color book tells of the princesses' daily adventure living in the castle. The series features artwork from the art masters whose works have entered the public domain and are no longer restricted by copyright. 

Who is the princess castle series for? 
I wrote the series primarily for girls age 7-12 but although it is a princess type story with mystery, action, and adventure, I feel even a boy could enjoy the series. (Bear in mind these are princess stories for girls, essentially.) It being a full-color illustrated ebook and paperback I hope to expose young readers to artwork from master artists of the world.
