Changeling by Philippa Gregory

Isolde

     Changeling is the first young adult novel by critically acclaimed historical-fiction by Philippa Gregory. Changeling is set in 1453 when every unexplainable thing is seen as the coming of the end of the world. I think that the best way to describe this book without giving it all away is to just introduce the major characters:

Luca Vero

Luca Vero- Luca is a handsome and intelligent young monk in training who is sent to investigate the oddities occurring all over Europe after being arrested for heresy.
Freize- Kitchen boy at the monastery where Luca lived. He is Luca's friend and constant companion.
Isolde- Is the daughter of a wealthy lord raised to believe that she will inherit her father's lands and castles. However, on her father's death her inheritance is usurped by her brother who demands she a marry a man of his choice, or become a nun. There is a growing bond between Luca and Isolde (Gasp!)
Ishraq- Is Isolde's companion having been raised alongside her. Ishraq is a Moor and so is therefore Muslim, being brought back by Isolde's father from his travels.

Changeling is the first book to be released in an upcoming quartet.
