A Cursed Moon was a fun little novella about the Wird Sister's unofficial big brother, Bren. While it's only a novella, it sure packs a lot of fun in. I was laughing out loud just about every few pages. Besides being hilarious, A Cursed Moon examines the relationship between Bren and Danny. They always appeared to be the odd couple and would fight like brothers. A Cursed Moon tells their origin story and lets us see a slice of their friendship outside of the Wird Sisters. 
 (view spoiler)[O MY GOODNESS! Bren turns Danny into a werewolf to save his life! I loved the description of of Danny's gangly uncoordinated wolf. He's also a blue merle which is a rare wolf so there should be more magical developments coming down the line. (hide spoiler)] 
 A Cursed Moon is definitely worth the read if you love silly, irreverent humor and adventure. O and also there are ghosts that fart. So there's that too...
