My daughter was interested in this, as she loves all things Peter Pan. I read it in an afternoon (older readers will have no problem with it) and as an adult, I thoroughly enjoyed it. However, for younger kids, it is a bit violent. If your kids can tell the difference between fantasy and reality, are not prone to nightmares, and enjoy a good adventure story, they will probably love this one. If they get scared easily, I'd avoid it for a bit... poisonous spiders, sword fights, and a guillotine can leave one a bit frightened.
More mature younger readers will also be fine with it, less mature older readers will need to be left to the parents judgment.
because im a fan of all misunderstood villians like King Jas. Mathews i just had to read this book cause hes just an intereasting caracter hes evilness is cause by so many trying times first off he doesnt have a mom his motherly figure is a family friend he calls Aunt Emily, secondly his dad never sees him, third he gets called a basterd by colleges, and yet seems to me he acts like he embraces it and then seeks some what revenge, to me hes like a younger verision of Dr. Greggory House
This was a book I loved. It kicked off right away with James going to Eton, and challenging a 'big boy'. This may raise a few red alerts. There is much sword fighting, some whipping, and talk of violence. Then James falls in love with a princess. This raises no concern. There are a few kisses, but nothing extreme. A few concerns would be the violence and the social behavior. I loved this book, but if forced to would rate it ages 10 and up. This was a wonderful book, which I think you'll enjoy it if you read it.
