Series is loosly based on Clancys work. Basicly only few names and parts of backstory was taken from books. The rest is not so good written fan fiction. Especially Jacks and Cathys relation is totally rewritten to be more exciting, thrilling and have as much cliches as possible. If you like work of Tom Clancy and have read at least one book with Ryan, you might find difficult to enjoy this series. Oh and there is a lot less clever intrigues than in books. Most of it is quite easy to forsee.
