I haven't read the first book in this series (though I have it on hold at the library) so I'm not sure how much of what is mentioned is spoilery. Hopefully not too much. Skyjack follows Thea Paris. The bit I read was her bringing some boys to their new home after their parents were killed in Africa. While not the full plot of this book, its a good little introduction to the book and I'm excited to read more.
