There are going to be many, many adults who love this book and yet I'm going to give it only 2-Stars... and here's why.
First, this book is supposed to be for the tween to young adult market, and for this market it has some problems, the first being the pacing. Susan Cooper's writing is poetic and descriptive, which adults like, but that doesn't necessarily translate into a good read for younger folks. It takes, for example, all of the adventure and sense of danger out of being attacked by a wolf.
Second, the narrative is split, and split in a way that again, I don't think is very appealing to Tweens and Teens. There's Little Hawk at first, and then there's John. And the story covers a long time span, which some of the intended audience is going to have difficulties relating to.
Now having spoken from my Mom-is-examining-this-book-for-her-kids-and-her-kids-blog point of view, let me tell you what did not work for me: the narrative is flat, unexciting, and preachy.
**EVER SO SLIGHT SPOILER POTENTIAL HERE**
Here is an example that I think shows all three shortfalls. It's an example of John's IMMENSE anger at his Step-father's telling him that he is an unworthy cretin not worthy of marrying a servant, and that if he doesn't tow the line that he (Kelly, the stepfather) will destroy him and any chances he has of making a living:
-------
"Anger was flooding through him, bursting out of its
long suppression. 'If you had been honest men, you
would have confess your mistake openly to all, and
asked forgiveness of God!"
Daniel (another character) grabbed him, pinning his
arms to his sides. "Stop!"
John stopped. He stood still; he took a deep breath.
He looked hopelessly at his stepfather, a God-fearing,
bigoted man who happened to be in the wrong place at
the wrong time nine years before."

END OF THE **EVER SO SLIGHT SPOILER POTENTIAL HERE**
That's it. Nothing left out. These were the signs of John's great rage. Okay for many adults, but a bit underplayed for me and I have to think, also for 'target' audience.
GHOST HAWK gives some accurate portrayals of that era. It portrays the brutality of Pilgrim fathers very well. But for all of that, GHOST HAWK is not a book I'm going to suggest to my tween and teen. Just not interesting enough. I can't remember which book I read about Mary Jemison, but this story, based upon true events, was much more engaging and educational. I even enjoyed YEAR OF THE BEAVER more, although it's flawed as well. And older readers who really want a unique view of how much more enjoyable it was to be an Indian than a white settler should search up James Axtell's paper, "The White Indians of Colonial America."
