I don't know that it would change your mind but I've read 8 books in the series and quite enjoy them. Great thrillers which focus mainly on the quirky and enigmatic FBI agent, Aloysius Pendergast, but also feature many of the same characters throughout the series. Although I wasn't reviewing books at the time I read these, I think I have rated most of them as 4 star reads.
Thank you! Fun is such an easy word, sometimes I feel bad for using it to describe the books I read. But honestly, fun sort of just captures exactly how it felt. So fun it is!
