Sunny Skyland last saw her twin sister when she was 3. She wants nothing more than to find her. When she discovers some extra money, Sunny takes off on an adventure to find her sister. A true adventure story, Runaway Twin by Peg Kehret (Lexile 740; Reading Level: Grades 4-7) gives us a character with real guts who learns how to stick up for herself and follow her dreams, no matter the cost.
I lost track of time in this book because Sunny went through one adventure after another in almost dizzying succession. She meets some people who help her out, and some who make her way more difficult, but her survival will surprise you.
One of the reasons I became an elementary school librarian is so I can read children's books.
