Ok, first I love this authour! I have met her, have all of her books that are still available, and can't wait to get her new books.
That aside, this is the second book in her Chronicles of Nick series, and it was just as good, if not better than the first!
The book is the story of Nick Gautier, a major minor character in her adult books. It provides major back story, and I don't want to give too much away, but if you read her adult books, her junior fiction is just as enthralling, just lacking the sex scenes.
I actually share these books with my Girl Guides, so I recommend for you too!
