Keeper of the Lost Cities was a fascinating series by Shannon Messenger. There are currently nine books in this series though Shannon Messenger has confirmed there will be a 10th book. This series circles around a girl named Sophie. She is an elf that was placed with humans. As the story continues, Sophie uncovers more of her elf powers, i.e., she is a telepath-someone who can read minds. My favorite character is Sophie because she is kind and makes a lot of friends. Another reason I like Sophie is that I can connect with her. Sophie has a sibling (like me), she also has a lot of friends (like me).
In conclusion, I thought Keeper of the Lost Cities was a remarkable series. If you like fantasy books or action books, you should definitely read Keeper of the Lost Cities. I rate this series 5 out of 5 stars.
