My nine year old daughter loved it, now her friends are borrowing it.
Format: Paperback
My nine year old daughter loved it. She read it the day she got it, and then re-read the first two volumes. As a retired Language Arts teacher, books like this warm my heart. Excellent engaging story line.

Great condition, beautiful artwork, great for a broad range of reading levels
Format: Paperback
My sisters are loving this series. We pre-ordered the 3rd graphic novel and they’re already asking if there will be a 4th! My sisters are both in 4th grade but sit at very different reading levels. “A” has a difficult time with reading comprehension and focus, so graphic novels have been a wonderful way to introduce her into the magical world of books. I firmly believe that graphic novels have helped her gain confidence and strengthen her reading skills… she now regularly reads chapter books! Sister “B” is a very strong reader; she loves both chapter books and graphic novels. Sorceline and Wings of Fire are her absolute favorites right now. This is a great option for when she still wants to be engrossed in a story but focus some more on imagery, giving her brain a break from the heavier stuff. We can’t wait to see if more books will be released in this series.
