The Why You Should Never series by Erin Nicholas runs thirteen books from 2009 to 2017. Each title is a warning that the characters promptly ignore: Why You Should Never Kiss Your Blind Date, Why You Should Never Kiss a Grump, Why You Should Never Kiss Your Ex-Husband, and ten more variations.
The series overlaps with the Bradfords books, sharing characters and settings. Some entries appear in both series. The title format gives the series a built-in hook, and the premise of each book is baked right into the name.
