Charlie Bone and the Invisible Boy, the third book in the author's planned quintet, begins when the magically "endowed" Charlie and his friend Emma discover a mostly invisible, strawberry jam-loving boy named Ollie Sparks imprisoned in the attic of the Hogwartsian Bloor's Academy. Ollie's plight is part of a seemingly amorphous Larger Evil Plot involving school authorities, a blue boa, and Charlie's three horrible great aunts. Charlie Bone and his friends are eager to fight wrongdoing with their combination of special powers, but obstacles in all shapes and sizes abound. Can the children rescue Ollie, Charlie's uncle, Ollie's older brother, and the other hapless victims...or are the enemies too plentiful and powerful? Despite the likeable Charlie and a plethora of magical happenings (raining frogs, sorcerers who escape paintings, etc.), reading this 408-page fantasy feels like a bit like running a marathon where the finish line feels farther away with every step. Thankfully, the ending is a happy one. (Ages 10 and older) --Karin Snelson

The book is, in its basest form, about a boy who was made invisible by - who else - that wretched disaster of a magician, Ezekiel Bloor, and the efforts of Charlie and his faithful band of do-gooders to rescue him. But there is much more than an invisible boy for Charlie to worry about.

His best friend Benjamin has gone with his parents to Hong Kong, so Charlie has to find a way to keep Runner Bean occupied without Grandma Bone finding out about him. He is introduced to a new girl, Belle, who will be attending the academy, but not through the usual way - that is, not at the academy on the first day of classes. He is introduced to this girl, who is the most beautiful girl in the world and whose eyes constantly change color, at his own home by his horrific aunts and Grandma Bone. The manner of their introduction isn't lost on Charlie, and he is wary of her from the beginning.

His Uncle Patton leaves, mysteriously, speaking of "someone dangerous" that must be stopped from arriving, and Charlie finds himself without the comforting presence of his uncle, who has begun to serve as a very effective buffer between Charlie and the Yewbeams. When his Uncle finally returns, the manner of his return is such that Charlie feels compelled to revisit the painting of Skarpo the Sorcerer in the hopes that Skarpo can help his Uncle, but Charlie succeeds in doing two things: 1) adding mystery to the white wand he "stole" in book 2; and 2) unleashing a very unpleasant series of circumstances not only on Bloor's Academy but also on the people who live in the surrounding town.

As we are finding out, there is more to everything than meets the eye - even if some of it is rather obvious. And the universe is expanding, most satisfactorily. We can see possibilities for more books, and indeed it has been stated in at least one place that this is a projected series of five books.

I have only a few issues with the series in general, and the main one is: why does every book have to be centered around someone that the Bloors and/or Yewbeams are hiding or don't want to be found? And why does it make such little sense (to me at least - it's entirely possible that my tiny brain is missing something rather obvious) that the Bloors and/or Yewbeams don't want these kids found? Especially since this last book was action packed from beginning to end, and between Skarpo, Belle, Uncle Patton, and other minor subplots there was plenty around which to write a book. I hope that the next two books will use a more clever contrivance around which to center the story.

Last, AND THIS IS IMPORTANT FOR THOSE WHO THINK THESE BOOKS ARE POTTER RETREADS, I had an issue with what happened to Charlie at the end regarding a certain wand and a genealogical table (not the one in the beginning of the book).. I won't describe anything more, because I don't want to give the ending anyway. Anyway, this event seemed to be the most glaring Potter similarity yet, and I admit to actually gasping out loud when I read it. I assumed that Ms. Nimmo, as she is no stranger to children's entertainment, *must* have read Potter, and therefore I was dumbfounded, wondering why in the world she would do something like this. However, I wrote to Ms. Nimmo, and she confirmed that she has never read the Potter works, except when her publisher tells her to take a peek at certain parts. Given that she's never read the books, then, all of the Potter similarities are entirely accidental. This was an answer that pleased me greatly, for I have absolutely loved these books.
