I think Keeper of the Lost Cities is an awesome book. It really places me into Sophie's shoes. My favorite part is when Sophie catches Elementite. I think Dex is very nice and definitely has a crush on Sophie. When Sophie (and Dex) get kidnapped, I think the men drug her too much. Other than that, it's really exciting! I never imagined an elf world! I really think the author is creative with names and look forward to having kids like me enjoy her books, just like I did.
