A wonderful story
Format: Paperback
This book was absolutely charming. The art is visually appealing, and the story is easy to follow with minimal prior knowledge required for new readers. I'd definitely recommend it for young readers wanting something new.

Kid loves this series
Format: Paperback
My 7 year old loves this book! We got it here because the local Library doesn’t have it in stock yet. He has spent the first few days off of school reading and was so excited!

I WANT MORE
Format: Paperback
Really positive, energetic, upbeat character with interesting and balanced superpowers. Primer is a superior Ben 10 with access to three superpowers at a given time, but her powers require a suit, which is a good counterbalance. The Teen Titans are represented wonderfully and accurately. DC could turn this into an animated movie, and it would perfectly fit with the 2005 Teen Titans show. Also, Gretel Lusky's art is fascinating and charming. I want to see more of her art in Primer and other DC products. I was disappointed to see that Greta only draws the firsr chapter. Nicoletta draws the other two chapters, and her art sucks. Thankfully, the story is still engaging.
