All in all book 1-3 were entertaining and plush with humor.
Book 1 was the best!
Book two was ok.
Book 3 was better than I thought it would be, and ended in a way that had some highlights (the Iron Eagles were awesome), but ultimately abused the instincts of the Librarian in a way that he wouldn’t have fell for.
Maybe it it was done to set up future books in the series, but instead it just provided a good bookend — one that allowed me to move on without looking back for anymore in the series.
Perhaps if the author made the female characters less incompetent and annoying, the end would have had more impact. As it was, good riddance.
