Christina Jones has a "hook", something she uses in all of her books. She takes you into a world that you probably don't know anything about - jump racing, truck(lorry)driving, small fairs, etc. Now we get wingwalking! Walking on Air is another wonderful book about a woman who learns how to succeed because of her own strength. To CJ's credit, she makes these journeys believable - she does great research. She also has a very compassionate storytelling style, a way to mix the good and bad in characters - because her characters, like all of us, are far from perfect. As is often the case in her books, there is a main story with very strong parallel stories that are relevant to the main story. I had to laugh, I thought right from the start that Billie was making way too big of a deal about her "secret" - turns out the rest of the characters in the book agreed with me. There's a reason for this and it all comes out at the end - you may think you have it all figured out, but you don't - there are a few twists that you don't see coming (or at least I didn't). One teeny complaint - I'd like to have seen about 4 more pages, just enough to know that all really was well and that Billie would be flying high forever! Another wonderful book - by all means, buy it!
