Sometimes I am SO tired I feel this way, but really this refers to the books (and TV show I’m told). In my school library they are very popular. I wasn’t certain at first how appropriate they would be for a middle school age group, but 5th graders through 7th graders are hooked on them and can’t get enough.  It seems like there are the comic books of the series and and also graphic novels. I ordered both, but have only gotten the graphic novels (hardcover) so far. Is anyone a fan of the TV show? Seems it is originally intended for an adult audience.
