First, I loved the illustrations. Incredibly well done, and there's a lot of it. The story itself is actually quite interesting, but the juxtaposition of science, with the fantasy world of the earth's core, plus a magical knife that cut everything seemed like a cop out when Leo Geo says multiple times that he is going to use science to get himself out of situations.

This book is interesting primarily because of its creative physical format. The shape is short and wide but is intended to be read when turned sideways, so that the length of each page is essentially doubled. This should make it a fun read for kids, but it is a bit awkward to handle and/or store with other books. I found the book entertaining and informational, but with its non-color, pen-and-ink design, I kept wanting to get some colored pencils of fine-point markers to brighten it up! I think that this might even be a way to utilize the book, by getting the publisher's permission to photocopy any portion of it for students to add their creative talents to the illustrations. While it is an obvious candidate for sharing with science-minded students, it might also help interest students who are more visually and artistically oriented to learn more about a subject of less interest to them.

Leo Geo and His Miraculous Journey Through the Center of the Earth by Jon Chad has a long title and a long adventure — one that goes right through the center of Earth! Jon Chad mixes science fiction and science fact to create a memorable tween graphic novel.

Leo Geo has a giant drill and he plans to ride it through to the center of the earth. Along the way he'll point out the sites. He'll see unusual formations, magma and some unexpected residents!

As this is a book about digging, the reader is asked to turn the book on its side after the introduction. Thus most of the book is read like a flip book, making it awkward but fun to read.

In terms of artistic style and whimsy Chad's artwork reminds me of Windsor McCay (Little Nemo). He uses a bold line and intricate details to flesh out the subterranean worlds. ( )

Rated a bit higher than the story involves, because I liked the clever formatting. ( )

Love Leo Geo! A fun blend of facts and fantasy of journeying to the center of the Earth. Also love the design of the book, very clever concept that was very well done, art and text. Great read for boys that are into science and science-fiction. ( )
