This book was just meh for me. I liked Jessica's Guide to dating on the dark side and thought this sounded fun/exciting/up my alley but I wasn't a fan. Did u think it was horrible, no but I'm not sure teens will like it because I felt like it jumped around a lot at the end/beginning of chapters and was confusing. 
 I did however like Millie and her relationship with the librarian, it was cute. I loved how she was everyone needs a librarian (yes Millie you are right).
