A Magical Start to an Epic Series
Format: Paperback
I read Amulet: The Stonekeeper with my class, and the students couldn’t get enough of it! The artwork is absolutely stunning, and the story grabbed their attention right away. Even reluctant readers were eager to see what happened next. The mix of fantasy, adventure, and relatable characters makes it the perfect series to hook middle-grade readers. As soon as we finished, they were already asking for the next book in the series!

I thought of it as a fantastical family adventure. Great artwork Wonderful Story
Format: Kindle
First thought You killed someone in the first few pages of a kids book! Wait Disney movies kill people off too. Okay, shock over.
I likes how the mother helped keep the kids upbeat when the moved into the old home and had to clean it and on the way there she was understanding of their feelings and was encouraging them to like their new home. Even encouraging Emily to learn more about her great grandfather. Just not be like him.
Emily was super brave for a kid who watched her father die and her mother get snatched by a monster. She took responsibility of her brother and the amulet and decided to help save her mother and the world that they were in. I liked the Emily has choices not just that she has to do something because she was given the amulet but she had the choice to. She also had the choice to seriously hurt someone but she made the choice to let him live even though he wasn't the nicest of beings. I like that she lets her younger brother help out and notices when he might be better suited for the situation because of his past favorite past time ( like my son, most kids and some adults...its gaming)
The story was great. A little dark but you get the whole light at the end of the tunnel feeling. That the characters will achieve what the set out to do. I also enjoyed the whole family thing. The illustrations were wonderful. I even slowed down and went back to look at the artwork. I look forward to reading this series and being able to talk about it with my son. It was a great start to a fantastical adventure.
Now that I think about it I'd recommend this to kids around middle grade but like I said my son has been reading the series for awhile so, maybe use caution it does have monsters and evil doers and its a little dark but not so much that I wouldn't say you shouldn't read this with a younger kid. I'm actually thinking about starting it with my youngest soon.
Great characters, Wonderful story and artwork, a quick read ( at least for me, an adult), fantastical adventure. I'll continue to recommend it to others and look forward to reading it with my youngest and continuing the series.

A perfect start
Format: Kindle
This is exactly the kind of graphic novel I was looking for. Full of sweetness with a little bit of bite. Reminds me of the great comic series bone. Great story, great art, I can’t wait to get into the next chapter.

Draws You in to the Series
Format: Paperback
The Stonekeeper is the first volume in Kazu Kibuishi's graphic novel series. Although aimed at middle school, it is good for upper elementary school children, and is enjoyable for adults as well. 2 years after the death of Emily and Navin's father in a tragic car crash, Karen moves her children to the family's old house in a dense forest. Built by Karen's grandfather Silas who then disappeared, it has been abandoned for years. During the first night, they hear a strange noise, and Karen is captured by an Arachnopod, a creature from a parallel world, Alledia. Emily and Navin follow their mother into the parallel world where they find their ailing great-grandfather Silas. He tells Emily about the power of the amulet she found in his house. It is the key to ruling Alledia. Silas expires, but not before instructing his robot and animal minions to aid Emily and Navin. This first volume, besides setting the story arc, narrates the rescue of Karen. Unfortunately, she is poisoned setting up the next volume for finding the antidote.
Besides an engaging story with compelling characters, Kibuishi is a fantastic illustrator. As with many exemplar graphic novels the spare text is amplified and much of the story told through his illustrations. The creatures of Alledia are strange enough to pique our imagination, but not so much that they are totally alien in form.
After reading Stonekeeper, I am eager to see what happens next with Emily and Navin, and their company.

wow
Format: Paperback
I remember when I read in reviews that kids had gotten sucked into this story and had become fans of this series so quickly.... Well, my daughter resisted till page 13 or 14... but since then she's in it... She's very picky when it is about books and even that she's 9, she started to read in English only a few months ago ( we lived abroad,she reads other language) so she still prefers books that is easy to read.
Anyway, get ready, this series is addicted... gooooood :) that is what we need :)
I mean, you can complain that this is a comic book but still, at least the child has the book in his/her hand and not a tablet... and at least he/she reads...
I'm really happy that I got this book for her.
