"Unhooking the Moon," by Gregory Hughes (Quercus), is one of the best books I have ever read. The story line is so good I can't explain it in words. It is intense and has a lot of action.
I think it is a great book for growing kids. The story is about a 10-year-old girl who has to find her own way after her dad passes away.
The one flaw in the book is that some of the language is a bit too mature for kids younger than 10. So if you think you are ready, read it.
