The main character is likable, interesting and loyal. He's a great friend. He's both clever and yet still a kid, so prone to doing dumb things.
This book is a delight. And it feels like it's written for kids, starring kids who act and think and speak like kids or young adults. It's refreshing after reading some clever books in which the kids are ideologically pure adults in kid form. Here the kids do dumb things that adults simply wouldn't do, like going into a stranger's house, into the basement without any adults knowing where they were. Or being told not to speak in the Quiet Wood (in case they are attacked) and two of the characters having a sparring match to see who can have the last word. Adults would tend not to do those things; but they are fairly natural to kids.
One of the issues of the book that would be worth discussing is how trust is earned. The main character is entrusted with an important secret because he demonstrates trustworthiness to the character carrying the secret. This is partly because of his loyalty and also because he shows himself to be the kind of person who will jump into a situation and help. In all the situations he does this, it turns out well. But it might not. What would happen if it didn't? How far should we go?
Cole, the main character, solves his fights by thinking. This would be a great conversation. How do his ideas help? How are they better than the other strategies by some of the other characters (like straight out fighting)? Where would his thinking need to start as he's trying to figure out what to do?
A wise parent would also have a conversation about entering strange people's houses. Ever. And not going into a stranger's basement. Ever.
There's fighting, real sword play. There's betrayal by grown ups. There is slavery. There is corrupt government and a king who has his daughters apparently killed in order to imprison them and steal their powers. So, lots of grown up stuff to deal with and discuss, but not too brutal with the details.
I like this book. I want to read the other four. 4 out of 5 stars.
