In my opinion, I really liked runaway twin. One reason why is because the girl has a big journey. Another reason why is because she will do anything to find her sister.  *****SPOILER ALERT*****  The last reason why is in a part she finds a big bag of money but asks anyone if it is theirs before taking it. My favorite part is she is she is adopted and she runs away to find her sister but doesn't tell her mom. You might like this book if you like mystery books. You should read this book because it makes you want to keep reading the book.
