Fast, fun and funny.
The biggest problem with this book is that first half of it felt like all exposition. It spent in an inordinate amount of time teaching & telling Kitty (and by default the reader) all about the Alpha Centauri Aliens. And surprise! letting her discover a ton of secrets about her own family background. To her credit the author tried to make it go down easy by masking it in quippy conversation punctuated by some action. But it really couldn't disguise that it was really just massive info-dump.
But the second part of the book kicks up into all action and makes up for the all the exposition.
I found myself with a goofy grin in the end. And even though I think the author needs to tone down the over-awesomeness that is Kitty (really, Kitty can do
everything and every guy wants her), I am looking forward to reading the next one.
