Crap Muffins- A Series?

Ok, books seriously need to put BOOK TWO in huge letters on the cover. It’s sooo annoying, I just got a book from the library, tried to read and said “wtf” only to realize it was a series and I hadnt read the 1st book. I had no idea whne I got it and now I’m mad, especially since I cant find the first book online. Grrr.
How do YOU feel about this?
