I love that in Discworld anything goes. Pratchett has created so many stories in this world because it has infinite possibilities. It's the only series I can think of that lets you read it out of order and even skip books without missing out on anything. I tend to gravitate toward the books featuring witchcraft or, in the case of Equal Rites, wizardry.
Magic in an unequal profession in Discworld - men are wizards, women are witches, and magicians are somewhere at the bottom of the barrel - for those possessed with magical acumen. Things get complicated when a dying wizard accidentally passes his magic down to a baby girl instead of a baby boy. Granny Weatherwax, an accomplished witch, attempts to train the young girl in the magic more associated with her gender, but quickly realizes Esk (the girl) has wizarding magic whether she likes it or not. So, they have to figure out how to debunk the stereotypes, which of course is extremely complicated, in order for Esk to learn how to properly use her magic before she hurts someone. This mission of creating equality in the wizarding world drives the rest of the action in the book and leads to some intense action and near-death experiences (and a lot of rain.)
Overall this book was entertaining and aligned with what I enjoy most about Pratchett but it definitely wasn't my favorite. I found certain spots hard to follow; some plot points felt very abrupt and I never really connected to any of the characters. Granny Weatherwax wasn't even that entertaining this time and she's a character I've liked a lot in the past. I would definitely recommend the Discworld series to anyone looking for something a little off kilter and comic, but maybe not this specific book.
Here are reviews I've written in the past for other Discworld books:
